Data Sheet T 8227 EN 2004-02 9

Principle of operationThe process medium flows through the butterfly valve. The flowcoefficient is determined by the opening angle of the disc. In Type 3331/BR 31a, the actuator motion is transmitted usinga square-ended shaft. In Type 3331/3278, a feather key isused to transmit the motion from the actuator to the shaft. The shaft is sealed by a packing.

Fail-safe positionDepending on how the actuator is attached (see Data SheetsT 9929 EN and T 8321 EN), the valve provides two differentfail-safe positions:Valve CLOSED without supply airThe butterfly valve is closed when the supply air fails. Valve OPEN without supply air The butterfly valve is opened when the supply air fails.

Notes on the differential pressure tablesThe specified Kv values apply for a nominal opening angle of ϕ100 = 70°. In addition, the following applies: ∆p0 Permissible differential pressure with disc in closed

position(valve CLOSED)

∆p100 Permissible differential pressure with a nominal opening angle of ϕ100(valve OPEN 70°)

The permissible differential pressures are limited by the nominalpressure ratings (also see T 8000-2 EN). Only on-off butterfly valves can be used without positioners. Inall other cases, positioners are required.

Principle of operation (Fig. 3)The process medium can flow through the butterfly valve in ei-ther direction. The position of the butterfly disc (3) determinesthe flow across the free area between disc and body (1). Theshaft (2) is sealed by a PTFE V-ring packing (9) which is loadedby Belleville spring washers (10) on top of the packing chamberand requires no maintenance.Butterfly valves are sealed between the disc (3) and seat. The di-rection of flow as well as the differential pressure determine thebreakaway torque required to open the valve. The double ec-centric bearing design has the effect that the disc only remainsin contact with the seat over a very small angle of rotation as itopens and closes. This reduces wear and increases the servicelife of the valve. Additionally, it reduces the breakaway torque.

Direction of flow (Fig. 3)The direction of flow "A" is recommended for throttling service,whereas the direction of flow "B" is recommended for shut-offservice.

Fail-safe positionAttached to the Type BR 31a-SRP Rotary Actuator, the butterflyvalve has two fail-safe positions which become effective whenthe piston is relieved of pressure as well as when the supply airfails:Valve CLOSED without supply airThe butterfly valve closes when the supply air fails.Valve OPEN without supply airThe butterfly valve opens when the supply air fails.

Pneumatic Shut-off Butterfly Valve Type 3335/BR 31a

Data Sheet T 8220 EN 2004-02 27

Principle of operationThe process medium flows through the butterfly valve. The flowcoefficient is determined by the opening angle of the disc (4),i.e. the cross-sectional area between the disc and the body (2).The disc is connected to the actuator by means of the shaft andcoupling elements. The disc and the seat ring (3) come into contact with the processmedium. The seat ring also functions as a flange seal.

Fail-safe positionDepending on how the rotary actuator is attached, the butterflyvalve has two different fail-safe positions which become effec-tive when the pressure acting on the diaphragm is reduced orwhen supply air fails:Valve CLOSED without supply air,the butterfly valve is closed when the supply air fails.Valve OPEN without supply air, the butterfly valve is opened when the supply air fails.

The shaft (2) issealed from both sides by a V-ring packing (9). Butterfly valves are sealed between the butterfly disc (3) and theseat (4). The direction of flow and the differential pressuredetermine the breakaway torque to open the butterfly valve.The double eccentric bearing design of the shaft causes the discon opening and closing to remain in contact with seat only overa very small angle of rotation (see Fig. 4). This reduces wearand increases the service life of the valve. Additionally, itreduces the breakaway torque.When the process medium flows through the valve in direction"A" (Fig. 5), the butterfly disc is slightly lifted out of the seat froma certain differential pressure onwards. This reduces the brea-kaway torque. On calculating which actuator is required, in thiscase, select the breakaway torque for direction of flow "A" listedin Table 5. When the process medium flows through the valve in direction"B", the butterfly disc is pressed firmly into the seat as thedifferential pressure rises. A better tightness is achieved, how-ever, the breakaway torque also increases, as shown in Table5.

Fail-safe positionDepending on how the pneumatic rotary is attached to thebutterfly valve, the valve has two fail-safe positions whichbecome effective when the actuator is relieved of pressure orwhen the supply air fails:Valve CLOSED without supply air,the butterfly valve closes when the supply air fails.Valve OPEN without supply air,the butterfly valve opens when the supply air fails.

Pressure-temperature diagramThe operating pressures specified are limited by the pressure-temperature diagram. Should the effective values be above thelimit curve, please contact us for further advice.

Principle of operationThe process medium flows through the valve. The flow coeffi-cient is determined by the opening angle of the disc. The shaftwith the attached disc is connected to the actuator over couplingelements. The shaft is sealed by a stuffing box.

Fail-safe positionDepending on the actuator version, the butterfly valve has twodifferent fail-safe positions which become effective when thepressure acting on the diaphragm is reduced or when supplyair fails:Butterfly valve CLOSED without supply air,the valve is closed when the supply air fails.Butterfly valve OPEN without supply air, the valve is opened when the supply air fails.

Principle of operationThe process medium can flow through the butterfly valve in bothdirections. The valve flow coefficient depends on the openingangle of the disc and the area released between the disc andvalve body.The valve is sealed by a metal/graphite laminated seal stack(seat) inserted in between the body and the metal disc edge(LTR 43-1) or by the metal seat ring screwed onto the disc(LTR 43-2). The seat adapts itself to the disc or seat ring. Thefriction forces are minimized by the triple eccentric design of thedisc and shaft.

Fail-safe positionPneumatic rotary actuators have two fail-safe positions whichbecome effective when the actuator is relieved of pressure aswell as when the supply air fails:Valve CLOSED without supply airThe butterfly valve closes when the supply air fails.Valve OPEN without supply airThe butterfly valve opens when the supply air fails.

Principle of operationIn the segmented ball valve the medium flows into the convexface of the ball. When the valve is closed, the pressure acts onthe convex side of the ball. The flow coefficient is determinedby the opening angle of the ball.To reduce the wear on the body on using abrasive media, thedirection of flow can be reversed.

Fail-safe positionWith the Type SRP and Type 3278 Rotary Actuator the controlvalve has two fail-safe positions which become effective whenthe pressure acting on the piston or diaphragm is reduced aswell as when the supply air fails: Control valve CLOSED without supply airThe segmented ball valve is closed when the supply air fails. Control valve OPEN without supply airThe segmented ball valve is opened when the supply air fails. The Type DAP Rotary Actuator has no springs. A defined finalposition is not reached when the supply air fails.

Selection of the flow characteristicThe design of the segmented ball allows the same valve to beused with two different types of flow characteristic:Equal percentage (standard)The actuator turns clockwise (right turning) to close the valve,looking from the actuator towards the valve.LinearThe converted actuator turns counterclockwise (left turning) toclose the valve, looking from the actuator towards the valve.

Principle of operationThe process medium can flow through the full bore of the ballvalve in either direction. The ball (3) with its cylindrical bore(ball channel) rotates around the center axis. The rotary angleof the ball determines the flow rate across the free area betweenthe body (1) and the ball channel. The ball shaft, which isguided to the valve exit, can be optionally connected to apneumatic actuator or equipped with a manually operated leveror manual actuator.The ball is sealed by means of exchangeable seat rings (4). Theball shaft is sealed with a maintenance-free, spring-loaded PTFEV-ring packing (9). The packing is loaded by Belleville springwashers (10) which are positioned above the packing.

Fail-safe position Depending on the rotary actuator version, the ball valve has twofail-safe positions which become effective when the pressure isreduced or when the supply air fails: Control valve CLOSED without supply airThe ball valve closes when the supply air fails.Control valve OPEN without supply air The ball valve opens when the supply air fails.

Principle of operation (Fig. 3)The process medium can flow through the Type BR 20a BallValve in either direction.The ball (3) with its cylindrical bore (ball channel) rotatesaround the center axis. The rotary angle of the ball determinesthe flow rate across the free area between the body (1) and theball channel. The ball shaft, which is guided to the valve outlet,can be optionally connected to a pneumatic actuator over anadapter or equipped with a manually operated lever.The ball (3) is sealed in the PTFE lined body by means of ex-changeable seat rings (3). The ball shaft is sealed with a mainte-nance-free, spring-loaded PTFE V-ring packing (9). The pack-ing is live-loaded by Belleville spring washers (10) locatedabove the packing.

Fail-safe positionDepending on the version of the single-acting rotary actuator,the ball valve has two fail-safe positions which become effectivewhen the actuator is relieved of pressure as well as when thesupply air fails:Control valve CLOSED without supply airThe ball valve closes when the supply air fails.Control valve OPEN without supply airThe ball valve opens when the supply air fails.

NoteThe ball valve can also be used for throttling service. Refer to thePfeiffer Data Sheet DB20a-kd in this case.Prior to using the ball valve in hazardous areas, refer to themaintenance instructions BA20a concerning its use accordingto ATEX 94/9/EC.

Principle of operationThe Maxifluss double eccentric plug rotates into the seat at anangle that eliminates sliding over the seat surface. This doubleeccentric design causes the plug to lift away and clear the seatimmediately as it starts to rotate without any breakaway torquewhen the plug shaft is turned from the closed into the openposition. The valve opens smoothly and therefore shows a stablecontrol response at small opening angles. The process mediumcan flow through the valve in either direction.The standard direction of flow is for– Liquids = flow to open FTO (direction of flow "V"), – Gases and vapors = flow to close FTC

(direction of flow "H") . The flow coefficient is determined by the opening angle of theplug.The inherent characteristic of the Maxifluss Rotary Plug Valvescan be converted into a linear or equal percentage charac-teristic using positioners and cam discs.

Fail-safe positionAttached to the Pfeiffer AT Type SC/SO Rotary Actuator, thecontrol valve has two fail-safe positions which become effectivewhen the piston is relieved of pressure as well as when thesupply air fails:Valve CLOSED without supply airThe Maxifluss Rotary Plug Valve is closed when the supply airfails.Valve OPEN without supply airThe Maxifluss Rotary Plug Valve is opened when the supply airfails.

Principle of operationThe shaft and the plug are arranged eccentrically, thus imple-menting the double-eccentric design of the Maxifluss rotaryplug valve together with the offset fulcrum (Fig. 3). This dou-ble-eccentric design ensures that the plug clears the seat imme-diately without any initial breakaway torque or friction whenthe plug shaft is turned from closed to open position. The valveopens smoothly, providing a stable control response at smallopening angles.The process medium can flow through the Maxifluss rotary plugvalve in either direction.The standard direction of flow for– Liquids = flow to open FTO

direction of flow “V“– Gases and vapors = flow to close FTC

direction of flow “H“The flow coefficient is determined by the opening angle of theplug.The inherent characteristic of the Maxifluss rotary plug valvescan be converted into a linear or equal percentage characteris-tic using positioners and cam discs.

Fail-safe positionThe control valve offers two possible fail-safe positions in com-bination with the VETEC Type R Diaphragm Actuator in case thesupply air fails:Valve CLOSED without supply air; the Maxifluss rotary plugvalve is closed when the supply air fails.Valve OPEN without supply air; the Maxifluss rotary plug valveis opened when the supply air fails.

Maxifluss Rotary Plug Valves withLow-noise TrimsSM 1.x ... SM 4.x

ApplicationValve components designed to reduce the noise level forinstallation into Types 72.x and 73.x Rotary Plug Valves

When controlling gases or vapors, the noise emission gener-ated by the control valves and the attached pipeline depends onthe free jet that forms at the vena contracta and its turbulent mix-ing zone.The Series SM 1.x to SM 4.x Low-noise Trims represent particu-larly effective and cost-efficient noise-reducing features as theyshorten the free jet and speed up the energy exchange in themixing zone when controlling gases and vapors.

Special features• Effective, reliable, and low-cost trims designed to reduce the

noise level• Face-to-face dimensions of the valve remain unchanged• Retrofitting possible• Effective in either direction of flow• Adaptable to specific operating conditions

VersionsThe trims are available as seat ring, cone or as a combination ofseat ring and cone.

Direction of flow “flow to open“ (FTO):– SM 1.0 ⋅ Perforated seat ring– SM 2.0 ⋅ Short perforated cone– SM 3.0 ⋅ Long perforated cone– SM 4.0 ⋅ Perforated seat ring plus short perforated cone

Direction of flow “flow to close“ (FTC):– SM 1.5 ⋅ Perforated seat ring– SM 2.5 ⋅ Short perforated cone– SM 3.5 ⋅ Long perforated cone– SM 4.5 ⋅ Perforated seat ring plus short perforated cone

Further versionsLow-noise trims for liquids

Principle of operationThe plug acts as the variable resistance that throttles the mediumflow. The low-noise trims split the entering or exiting medium jetinto small jets with a short free jet.The energy exchange in the mixing zone is sped up, reducingthe noise level by up to 20 dB compared to a standard valve.


Direction of flowThe process medium can flow through the Maxifluss rotary plugvalves in either direction.For gases and vapors, the preferred direction of flow is “flow toclose“ (FTC).In special cases, the valve can also be used with direction offlow “flow to open“ (FTO).The Types SM x.0 and SM x.5 Low-noise Trims must be selectedaccordingly (refer to Figs. 4 to 11).

Principle of operationThe signal pressure pst generates a force at the piston surfacewhich is balanced either by the compression springs in the actu-ator (single-acting version) or by a corresponding counterpres-sure (double-acting version).The force generated at the pistons is converted into a rotary mo-tion using the pinion shaft. The adjustable travel stops for OPENand CLOSED position allow the end positions to be finetuned to±4°.In the single-acting version, the spring return torque and the re-quired signal pressure are determined by the number ofsprings.Fig. 4 shows the usable air torques– MdLE for the single-acting version– MdLD for the double-acting versionand the usable spring torques MdF depending on the openingangle ϕ.

Fail-safe positionThe Type SRP Rotary Actuator offers two possible fail-safe ac-tions (rotary motions) in case the supply air fails or the pistonsare relieved of pressure. The rotation directions apply whenlooking from the actuator towards the valve."Springs turn clockwise"Springs rotate clockwise when the pressure drops."Springs turn counterclockwise"Springs rotate counterclockwise when the pressure drops.The Type DAP Actuator is designed without springs. The actua-tor does not move to a defined end position when the supply airfails.

Principle of operation (Fig. 2)The signal pressure pst generates a force at the diaphragmsurface which is balanced by the compression springs (4). Inthis process, the linear motion of the actuator stem (5), whichis proportional to the signal pressure, is transmitted to the leversystem (6), where it is converted into a rotary motion. The upperand lower limits of the opening angle can be adjusted using thetwo externally accessible stop screws (8).The bench range and useable actuator torque are determinedby the number of springs and their compression.The final control element can be connected to either flange 1 or2. For both connections, the flange dimensions and sleeveshaft (7) with four feather key notches are designed accordingto DIN ISO 5211.In case the signal pressure fails, the connected valve moves tothe predetermined fail-safe position, in which the actuatorsprings (4) either close (fail-close) or open (fail-open) the finalcontrol element depending on the respective fail-safe action andwhether the final control element is attached to flange 1 or 2.

Fail-safe position Control valve CLOSED when the supply air failsThe springs close the connected final control element wheneverthe pressure acting on the diaphragm decreases or the supplyair fails. Control valve OPEN when the supply air failsThe springs open the final control element whenever the press-ure acting on the diaphragm decreases or the supply air fails.

Torque characteristic curve (Fig. 3)The characteristic of torque is determined by the lever design.Fig. 3 illustrates a typical example of the useable air torques MdLand useable spring torques MdF plotted versus the openingangle ϕ.

Pneumatic Rotary Actuator


ApplicationSingle-acting pneumatic rotary diaphragm actuator for butter-fly valves and other final control elements with rotary closuremembersMaximum opening angle ϕ = 93°

The Type BR 30a Pneumatic Rotary Actuators are equipped witha rolling diaphragm and a central return spring.

Special features• Effective diaphragm areas from 600 to 1300 cm²• Torques from 15 to 5619 Nm• Signal pressure up to max. 6 bar• Various bench ranges possible through continuously adjust-

able spring compression or variation of the springs• No special tools needed to change the bench range• Direction of action (spring opens/closes) depends on attach-

ment to the valve• Externally adjustable stop screws to limit the opening angle• For continuous operation at temperatures from −35 to 90 °CAttachment of positioner, limit switch, solenoid valve, and otheraccessories possible

Data Sheet T 9930 EN 2003-12 143

Principle of operation (Fig. 3)The signal pressure generates the force F = pst ⋅ A at diaphragmsurface A (2). This force opposes the force of the compressionspring (4) in the actuator. In this process, the linear diaphragmtravel H is transmitted to the actuator shaft (13) over the actuatorstem (3) and the levers (11 and 12), where it is converted into arotary motion. The upper and lower limits of the opening anglecan be adjusted using the two externally accessible stopscrews (14).The travel H is proportional to the signal pressure pst. The signalpressure range is determined by the spring rate and the springcompression, which can be modified within a wide range byturning the threaded rod (7). Each actuator size is by defaultequipped with two different springs. Spring 1 can be used forpressures up to 3.5 bar, spring 2 up to max. 6 bar.The valve can be attached to either end of the shaft (13). Bothconnections are designed as a square socket according toDIN/ISO 5211. The connection determines the actuator’sfail-safe action:

Fail-safe action “Spring closes”The compression spring (4) closes the valve when the dia-phragm is relieved of pressure or when the supply air fails. Thevalve is opened against the force of the spring when the signalpressure increases.

Fail-safe action "Spring opens"The compression spring (4) opens the valve when the dia-phragm is relieved of pressure or when the supply air fails. Thevalve is closed against the force of the spring when the signalpressure increases.

Torque characteristic curve (Fig. 4)The characteristic of torque is determined by the lever design.Fig. 4 illustrates a typical example. The diagram plots the airtorque MdL and the spring torque MdF versus the actuator’sopening angle ϕ for a certain actuator size. The air torque re-sults from increasing the signal pressure pst against the springforce; the spring torque results from pst = 0, when the spring isrelieved from its rest position.
