DescriptionType 1051 and 1052 Size 33 spring-and-diaphragm ac-tuators are used on rotary-shaft valve bodies for throt-tling or on-off applications. The Type 1051 may be usedfor on-off service without a positioner or for throttling ser-vice with a positioner. The Type 1052 uses an adjust-able spring seat to control spring compression. It may beused for on-off service without a positioner, or it may beused for throttling service with or without a positioner,depending on service conditions.
A top-mounted handwheel may be mounted for infre-quent service as a manual override. A manual actuatoris recommended for routine and repeated manual op-eration. Externally adjustable travel stops are used tolimit the degree of rotation at both ends of the actuator
stroke. Provisions are included for integral mounting ofoptional magnetic proximity switches. Lever-operated,mechanical switches are also available.
The lever for the Type 1051 and 1052 size 33 actuatoris supported by bushings. The lever may be changed toaccommodate valve bodies with different size valveshafts and different mounting adaptations. Levers andaccessories are available for mounting valve bodies andequipment with the following mounting adaptations:
F and G mounting adaptations (figures 9 and 10)are for use with Fisher Splined-shaft rotary valve bod-ies with 1/2, 5/8, and 3/4 inch (12.7, 15.9, and 19.1mm) valve shaft diameters. A stub shaft is availablefor installation on the end of the lever opposite thevalve body for use as a wrench-operated extension
Types 1051 & 1052 Size 33

(for emergency override) or as a means of connectinga manual actuator (see figure 14).
H mounting (figure 11) is for use with non-Fisherproducts and user-provided mounting brackets andshaft couplings. It includes a mounting surface withthreaded holes for attaching the user-provided mount-ing bracket. A 7/8 inch (22.2 mm) stub shaft with flatsis pinned to the lever and is used to couple the actua-tor to the operated equipment. A second stub shaftmay be installed on the opposite end of the lever foruse as a wrench-operated extension (for emergencyoverride) or as a means for connecting a manual ac-tuator (see figure 14). Stub shafts are available instandard and reverse constructions (see figure 12) toprovide proper operation with the mounting positionand actuator action desired (see figure 2).
J mounting (figure 13) permits use of the actuatorwith Fisher Controls keyed-shaft valve bodies and oth-er keyed-shaft equipment with 3/8, 1/2, and 5/8 inch(9.5, 12.7, and 15.9 mm) shaft diameters. A stub shaftis pinned to the lever and a valve shaft coupling ispinned to the stub shaft. The coupling has multiplekeyways (see figure 4) to accommodate mounting inthe desired position. A second stub shaft may beinstalled on the opposite end of the lever for use as awrench-operated extension (for emergency override)or as a means for connecting a manual actuator (seefigure 14).
Specifications
Specifications are shown in table 1 for Type 1051 and1052 size 33 actuators. Some specifications for a giv-en actuator as it originally comes from the factory arestamped on a metal nameplate attached to the actua-tor.

WARNING
To avoid personal injury or propertydamage caused by bursting of pressureretaining parts, be certain the dia-phragm sizing pressure does not ex-ceed the diaphragm sizing pressure lim-its listed in table 1. Use pressure-limiting or pressure-relieving devices toprevent the diaphragm sizing pressurefrom exceeding these limits.

The actuator, as it comes from the factory, is normallymounted on a valve body. Follow the procedures givenin the valve instruction manual when installing the con-trol valve in the pipeline.
If a positioner is ordered with the actuator, the pres-sure connection to the actuator is normally made atthe factory. If it is necessary to make this connection,run either 1/4-inch pipe or 3/8-inch tubing (for standarddiaphragm case fittings) between the pressure con-nection and the instrument. Keep the length of tubingor pipe as short as possible to avoid transmission lagin the control signal.
When the control valve is completely installed andconnected to the controlling instrument, check to makesure that the action is correct (air-to-open or air-to-close) and that the controlling instrument is properlyconfigured for the desired action. For successful op-eration, the diaphragm rod, lever, and valve shaft mustmove freely in response to changes in the loadingpressure on the diaphragm.
Actuator Mounting and ChangingActuator MountingUse the following steps to mount the actuator or tochange actuator mounting style or position.
F and G Mounting AdaptationsUnless otherwise specified, key numbers referenced inthe following procedures are shown in figure 9 for theType 1051 actuator and in figure 10 for the Type 1052actuator.

11. Refer to the table of contents for accessory instal-lation procedures.
Type 1052 Spring CompressionAdjustment
Initial CompressionKey numbers referred to in this procedure are shownin figure 10 unless otherwise specified.
The Type 1052 nameplate specifies an initial set ad-justed into the actuator spring. Initial set is the casingpressure at which the diaphragm (key 3) and dia-phragm rod (key 10) begin to move away from thestop in the upper diaphragm case (key 1) when theactuator is disengaged from the control valve body orother operated equipment. The initial set was deter-mined from the service conditions specified when theactuator was ordered, so that when the actuator andvalve are in service, the valve ball or disk seats prop-erly and full travel is obtained with the supply pressurespecified on the order and shown on the nameplate.
Before adjusting spring tension to change initial set,the valve body or other operated equipment must beremoved or otherwise disengaged from the actuator.Refer to the applicable steps given under the appropri-
ate mounting adaptation in the Actuator Mounting andChanging Actuator Mounting procedure.
To gain access to the spring adjusting screw, eitherthe spring adjuster cover (key 117) or the switchmounting plate (key 59) must be removed. If externallymounted switches are used, remove them as an as-sembly by removing the cap screws (key 75, figure 16)and the switch mounting plate (key 1, figure 16). Inorder to gain access to the cap screws, it may be nec-essary to loosen the hex nuts (key 77, figure 16) andslide the switches away from the actuator housing.
Note that the lower part of the spring adjusting screw(key 74) is notched so that it can be rotated with ascrewdriver or other flat bladed tool. To decreasespring compression, rotate the spring adjusting screwto the right (see figure 5). To increase spring compres-sion, rotate the spring adjusting screw to the left(clockwise when viewed from above). Adjust thespring so that the diaphragm rod just starts to travel atthe initial set pressure specified on the nameplate.When the desired initial set has been achieved, installthe spring adjuster cover or switch mounting plate.
Stroking RangeKey numbers referred to in this procedure are shownin figure 10 unless otherwise specified.
If, under operating conditions, the desired strokingrange cannot be achieved with the casing pressureused, it may be possible to shift the stroking range bymaking a spring adjustment to change the initial springcompression. A spring adjustment shifts the casingpressure span and equally increases (or decreases)
1. For more detailed information concerning proper spring selection to obtain thetorque required, consult your Fisher Controls sales office or sales representative.
the casing pressure at which the actuator begins tostroke and the pressure at which the actuator reachesfull travel.
To gain access to the spring adjusting screw, eitherthe spring adjuster cover (key 117) or the switchmounting plate (key 59) must be removed. If externallymounted switches are used, remove them as an as-sembly by removing the cap screws (key 75, figure 16)and the switch mounting plate (key 1, figure 16). Inorder to gain access to the cap screws, it may be nec-essary to loosen the hex nuts (key 77, figure 16) andslide the switches away from the actuator housing.
Note that the lower part of the spring adjusting screw(key 74) is notched so that it can be rotated with ascrewdriver or other flat bladed tool. To shift the cas-ing pressure span downward, rotate the spring adjust-ing screw to the right (see figure 5). To shift the casingpressure span upward, rotate the spring adjustingscrew to the left. When the desired stroking range hasbeen achieved, replace the spring adjuster cover orthe switch mounting plate.

Actuator parts are subject to normal wear and must beinspected and replaced as necessary. The frequencyof inspection and replacement depends upon the se-
verity of service conditions. Instructions are given be-low for disassembly and assembly of parts. Key num-bers referenced in the following steps are shown infigure 9 for the Type 1051 actuator and in figure 10 forthe Type 1052, except as listed below or otherwisespecified in the procedures. If new parts are requiredfor repair or to change construction, use only genuineFisher Controls replacement parts.
Mounting AdaptationsF and G Adaptations
The procedures given in this instruction manual applydirectly to F and G mounting adaptations. Refer to fig-ures 9 and 10.
H Mounting Adaptations
Whenever the procedures require separating the ac-tuator from the operated equipment, it may be neces-sary to remove brackets, couplings, and stub shaftsbefore proceeding. Refer to figure 11 for parts usedwith the H mounting adaptation.
J Mounting Adaptations
Whenever the procedures require separating the ac-tuator from the valve body, it may be necessary to re-move couplings and keyways. Refer to figure 13 forparts used with the J mounting adaptation.
WARNING
Avoid personal injury or property dam-age from sudden release of processpressure or bursting of parts. Beforeperforming any maintenance opera-tions:
� Disconnect any operating lines pro-viding air pressure, electric power, or acontrol signal to the actuator. Be surethe actuator cannot suddenly open orclose the valve.
� Use bypass valves or completelyshut off the process to isolate the valvefrom process pressure. Relieve processpressure from both sides of the valve.Drain the process media from bothsides of the valve.
� Vent the power actuator loadingpressure and relieve any actuator springprecompression.
� Use lock-out procedures to be surethat the above measures stay in effectwhile you work on the equipment.

WARNING
Failure to control spring tension againstthe upper diaphragm case as outlined inthe following step could result in sud-den spring decompression causingbodily injury or equipment damage.Control spring tension by following step3 closely.
3. Loosen the hex jam nut (key 84 for Type 1051, orkey 86 for Type 1052) on the up travel stop. This stopis nearest to the positioner or positioner cover (key 39;also see figure 3). Screw the travel stop in (turn itclockwise) until it can be verified that all spring tensionhas been removed from the diaphragm stop in the up-per diaphragm case, i.e. when any movement of thetravel indicator pointer is observed, all spring tensionagainst the upper diaphragm case stop has been re-moved. Do not rotate the travel stop past this positionas additional compression of the spring is not neces-sary or desirable.
4. Carefully remove all cap screws and hex nuts (keys5 and 6) from the diaphragm case.
5. Remove the diaphragm case and the diaphragm(key 3).
6. Inspect the diaphragm plate (key 4). If the dia-phragm plate is damaged or if further disassembly ofthe actuator is required, proceed to the DiaphragmPlate, Diaphragm Rod, Spring, and Spring Seat proce-dure.
7. Inspect the diaphragm and replace if necessary.
Assembly1. Place the diaphragm (key 3) on the diaphragmplate (key 4), making certain that it is properly cen-tered.
2. Make sure that the up travel stop (see figure 3) isscrewed in sufficiently to eliminate interference of thediaphragm plate (key 4) with the upper diaphragmcase.
3. Observe the correct position of the loading connec-tion fitting and install the upper diaphragm case (key
1). Replace the cap screws and nuts (keys 5 and 6)which secure the upper diaphragm case to the actua-tor housing. Tighten the nuts in an alternating fashion(see table 2).
CAUTION
When adjusting the travel stop for theclosed position of the valve ball or disk,refer to the appropriate valve body in-struction manual for detailed procedu-res. Undertravel or overtravel of manyvalve types may result in poor valve per-formance and/or damage to the equip-ment.
4. Adjust the up travel stop (see figure 3). If the uppertravel stop establishes the closed position of the valveball or disk, refer to the valve body instruction manualand follow the procedures given for properly establish-ing the closed position. Proceed as appropriate:
For F, G, and J mounting adaptations , perform op-erations beginning with step 8 under the appropriatemounting adaptation section of the Actuator Mountingand Changing Actuator Mounting procedure.
For H mounting adaptations, perform operationsbeginning with step 7 under the appropriate mountingadaptation section of the Actuator Mounting andChanging Actuator Mounting procedure.
5. Return the travel indicator pointer to its originalposition as previously marked on the travel indicatorscale.
6. Install the inlet piping to the upper diaphragm case.

Positioner Mounting1. Before installing the positioner, the positioner cammust be installed on the lever (key 10, figures 9 and10). Refer to the Installing the Cam procedure.
2. Refer to the positioner instruction manual for set-upand calibration procedures.
Top-Mounted HandwheelKey numbers used in this procedure are shown in fig-ure 17 except where indicated.
The optional top-mounted handwheel can be used asa manual actuator for intermittent service or as an ad-justable up travel stop to limit full retraction of the dia-phragm rod (key 10, figures 9 and 10).
The handwheel assembly is attached to a special up-per diaphragm casing (key 1, figures 9 and 10) withcap screws (key 141). A hex nut (key 137) locks thehandwheel in position. For field installation of a hand-wheel, the special upper diaphragm case must be or-dered as well as the handwheel.
Turning the handwheel (key 51) clockwise into the up-per casing forces the pusher plate (key 135) againstthe diaphragm and diaphragm plate (keys 3 and 4) tocompress the spring (key 11, figures 9 and 10) andmove the diaphragm rod downward. Turning the hand-wheel counter-clockwise allows the actuator spring tomove the diaphragm rod upward. If the valve is push-down-to-close, full opening can be restricted by posi-tioning the handwheel at the desired position. If thevalve is push-down-to-open, full closing of the valveball or disk can be restricted by use of the handwheel.
Instructions are given below for complete disassemblyand assembly required for inspection and parts re-placement.

3. Thread jam nut (key 128) all the way onto thethreaded bolt portion of the locking device beforethreading it into the cover (key 59).4. After the bolt is threaded into the cover, drive thegroove pin (key 127) into the threaded bolt. So thelocking mechanism will not interfere with rotation of thelever (key 27), rotate the locking mechanism counter-clockwise until it is stopped by the groove pin (key127). Attach the cover to the actuator with cap screws(key 60).5. Attach mounting plate (key 123) with cap screws(key 21).6. Be sure the diaphragm rod is retracted fully. Thiswill be the locked position of the valve.7. Screw the threaded bolt into the cover until it con-tacts the actuator lever.8. Rotate the locking device slightly until the hole inthe mounting plate (key 123) aligns with a hole in thelocking device.9. Tighten the jam nut against the cover.10. Insert the padlock (not furnished by Fisher Con-trols) to connect the mounting plate with the lockingdevice.
Operating the Locking Mechanism
To Unlock the Actuator1. Remove the padlock. Loosen the jam nut (key128), and unscrew the threaded bolt until it is stoppedby the groove pin (key 127) in the threaded bolt.
Note
For normal operation of the actuator,the threaded bolt must be unscrewed farenough that the actuator lever will notcontact the bolt in normal actuator op-eration.
2. If you are going to leave the bolt threaded into thecover, lock it with the jam nut (key 128) so that it can-not be screwed into the cover and interfere with nor-mal actuator operation.
To Lock the Actuator
1. Make sure the actuator diaphragm rod is retractedfully (the locked position of the valve). For a push-down-to-close valve and actuator, the valve will befully open when locked. For a push-down-to-openvalve and actuator, the valve will be fully closed whenlocked.
2. Make sure the jam nut (key 128) is loose. Then,screw the threaded bolt into the cover until it contactsthe actuator lever.
3. Rotate the threaded bolt until one of the holes inthe locking disk (which is welded to the bolt) is in linewith the hole in the mounting plate (key 123). Tightenthe jam nut against the cover.
