JIS 10K Aluminum Butterfly Valves

●Conform to the specification of JIS and Japanesegovernment officesIt conforms to the specification of JIS B2032 (wafer typerubber-seated butterfly valves) and Japanese governmentoffices as a valve used for supply water services or air-conditioning facilities, etc. in buildings.●Half of conventional type by weight! Super light-weightand slim body made of aluminum alloySince a body is made of aluminum alloy die casting (ADC12),which has light weight and excellent mechanical strength, itis a general-purpose butterfly valve that weight is as light as1/2 of cast iron butterfly valve, and 1/10 of JIS cast iron gatevalve, and dimension and height are as compact as 1/4 and1/2 when compared with a gate valve.●Excellent seat sealing capability and durabilityBy adopting spherical-surface disc and spherical-surface seatstructure, high seat sealing capability and low torqueperformance are sufficiently improved as compared withformer products, and the durability of rubber seat is improvedimmensely.●Dew condensation-proofThe thermal insulation yoke made of austenitic stainless steelis provided between valve body and actuator, and it blockstransfer of the fluid temperature to a valve operating deviceand will minimize the dew condensation. Moreover, it isdesigned with the easy structure for disassembly and recycleof the material.(Refer to the 18-page graph for dew condensation-proofcapacity.)

●Suitable for rusty water preventionBy only disc and rubber seat contacting fluid, red water (rustywater) doesn't come out of valve body.Disc : 18Cr(s)-12NiMo steel (SCS14A-316SS)Rubber seat : EPDM (NBR or FKM available upon request)●Long neck structure in consideration of constructionmethod and operabilityFor the minimum 62mm long neck structure under theactuator, the heat and cold thermal insulation is easily carriedout, and it does not have trouble in valve operation.(When thermal insulation is also carried out with gearactuator, the extended indicator kit is available upon request.--- Refer to 14-page)●Wide range of selecting operatorsLever handleWorm gearPneumatic actuator (double/ single action) + Fig.550

●Improvement of the flow rate characteristicsTo compare with, when Cv value of the conventional highperformance butterfly valve is 100, the value of gate valvebecomes 200 and more. It was difficult to achieve high flowwith lower pressure loss. Then, HIGH FLOW®-T/ H isdeveloped for the purpose that pressure loss is loweredimmensely with high flow. Thereby, Cv value which wasbelow a half of a gate valve has been improved to about 70%,and the performance which customes demand has beenrealized sufficiently.(Refer to Table 1 and sectional drawing)

●Lower torqueWith setting up an optimum position for the sealing point ofdisc and seat ring, and an eccentricity of disc and seat ring inthe valve, we developed new high performance butterfly valve,HIGH FLOW®-T/ H, with lower and excellent operationtorque.

●Upgrade the temperature characteristicThe volume of Teflon® seat has been lessened and theexcellent seat sealing capability from low temperature to hightemperature is realized by reducing the influence fromthermal expansion.

Special Specification

Attachment position for actuatorDue to the operation or the piping space, the position of anactuator such as lever, worm gear, electric or pneumaticactuators can be changed as mentioned below.

●Position I / Position II (Standard position)In case that the flow direction is restricted in HighPerformance Butterfly Valves, Position I becomes thestandard position when the flow comes from the left in thefigure shown, and Position II comes from the right.When installing the valve, please check the flow direction isthe same as the arrow on the valve body.

●Position III / Position IV (the quarter-turned positionfrom the standard)It is possible to adjust the actuator at the site. However, sincethe delicate adjustment for disc positioning is required, werecommend you to advise this request when ordering.

Indicator kit (extended indicator for thermal insulation)This kit is for an indicator that can be installed in case ofcovering worm gear unit with thermal insulation material.

●For Fig. 550GAThis indicator is for Fig. 550GA, 10K Aluminum alloy butterflyvalves on page 4.○The indicator can be easily installed to mount on a wormgear unit.

○Only by inserting on the existing gear unit, it is simplyattached.

○Because indicator is made with a plastic material, dewcondensation is minimized in case of cold water service.

○ It is possible to adjust length from 62mm to 75mmdepending on thermal insulation thickness.

○Since the back of indicator plate is adhesive, they can attachon thermal insulation.

○Available in size 40 to 200.

●For ductile iron butterfly valvesThis indicator kit is used in the following models.

○Depending on thickness of thermal insulation material, it ispossible to adjust within 35mm to 55mm.

Technical Data

The Cv value _ which is used by TOYO VALVE to indicate the capacity of a valve _ is a flow rate represented in terms ofU.S. gallons per minute when clear water at 60 F゚ flows through a valve, in which the differential pressure between itsoutlet and inlet is kept at 1 psi _ 6.89kPa.

The Cv value can be determined by experiment, and the relation between the Cv value and the flow rate or pressure drop,when the fluid is water.

In case of water, the pressure drop or the flow rate can be obtained by the following formulas.

ΔP ＝ 0.134 Q2GLCv2

ΔP ＝ pressure drop（MPa）

Q ＝ flow rate（m3/s）

Q ＝ 2.735Cv ΔPGL

GL＝ specific gravity of fluid when setting water to 1

Pressure-Temperature Rating■Rubber Seat

■ Dew condensation-proof capacity (Fig. 550)─ Relation between environment (temperature and humidity) and dew point temperature ─

●Application of Pressure-Temperature Rating(1) This diagram is prepared with based on maximumallowable working pressure and temperature, pressure-temperature characteristics of EPDM in JIS B2032 (Wafertype rubber-seated butterfly valves).In actual application, it is necessary to expect the safetyallowance in consideration of piping design conditions, etc.Generally, the following safety allowance is recommended.○ For large size10 - 15%.

○ For pulsated flow or steam (Teflon® or metal seat)20 - 25%.

(2) In case of applying some regulations, such as Japanesegovernment standards, etc., it may be restricted inmaterial, temperature, design, strength, etc. Beforehand,please refer to related regulation or standard.

(3) In JIS B2032, the maximum allowable flow verocity of fluidwhen the valve is fully opened is specified as 3m/ s atnominal pressure 10K and 4m/s at nominal pressure 16K,and 30m/ s in case of gas. If the flow verocity exceedsthese criteria, the pipe diameter should be revised.Note: 1. The maximum allowable working pressure is affected by the

mating flange when installing the valve with JIS5K flanges.Static water flow: 0.7MPaPulsated water flow: 0.6MPa

<Note> Critical zone… Boundary zone between dew condensationzone and non-dew condensation zoneThe figure is given certain range in consideration of atmosphericpressure by the difference in height above sea level and climate, thecircumstance around pipe, temperature change of the fluid in pipe (coldwater), dispersion of data, etc.

1. A rubber seat (NBR/EPDM) may deteriorate at an early stage in service for hot water supply line.2. An EPDM seated butterfly valve shall not be used for all oil applications.
