WRAS ApprovalAll KITZ EPDM seat materials are fully in accordance with latestWRAS standards.

Non-peeling seat-to-body constructionMoulded-in (bonded) seat structure is employed for 2” to 12”. Largersized valves are provided with replaceable seat. This non-peelingseat-to-body construction assures maintenance-free application forhigh fluid velocity service, vacuum service and handling surgingfluid velocity. It also guarantees peel-free valve mounting onpipelines.*1 4 meter / second maximum for on-off liquid handling.*2 Up to 30 torr.

Spherical design for discs and seatsRubber seats are spherically designed where they contact top andbottom stems. This protects widely designed rubber seats frompeeling or deformation for prolonged service life of valves. Thinlystreamlined metal discs are the results of elaborate laboratory studyto ultimately minimize the pressure loss.

Choice of materials and operating devicesChoice among 4 disc and 2 seat materials and manual, pneumatic orelectric valve operating devices makes service applications highlyversatile.*3 Additional seat materials available subject to requirements.

Integral ISO 5211 actuator mounting flangeAny pneumatic or electric valve actuators provided with ISO 5211valve mounting flanges can be easily mounted for actuation of valvesin the field.

Low valve operating torqueLow operating torques are designed low for extension of valveservice life and economic consideration in selection of valveoperating devices.

Light-designed for operation efficiencyDesigned much lighter than our conventional series for operationefficiency in piping

Emission-free stem sealing mechanismPrevention of external fluid leakage is maximized with a rubber O-ring assembled around the top stem and tight contact betweenspherically designed rubber seat and spherically designed top andbottom end of the disc.

Index plateIndex plate has 10 locking positions as standard.

Condensation-proofCondensation-proof type is optionally available with heat insulating plate(size 2” to 8”) or stainless steel stand (size 10” to 24”).

*Cv is defined as the flow in GPM that a valve will carry with a pressure drop of 1.0 psi, when the media is 60 ゚F (15.6℃) water.

Liquid flow:Q = CvQ = Liquid flow rate (gallons per minute)△P = Pressure drop across valve (psi)S = Specific gravity of media

Gas flow:Q = 1360 CvQ = Gas flow rate (SCFH－std. cu.ft./hr.)S = Specific gravity of gas (air=1.0)T = Temp.－degrees rankin ( F+460)△P = Pressure drop across valve (psi)P1 = Upstream pressure (psia) absolute

Note that △P must be less than .5(Flow is critical when △P is greater than .5 P1)

Valve Selection1. Ensure to select a valve with design specifications

which meet the fluid type and the pressure andtemperature conditions required.

2. Lubricants are applied to discs, rubber seats andPTFE seats as standard to protect their surfaces.Oil-free treated types are available as option. ContactKITZ Corporation or its local distributors for the details.

3. Contact KITZ Corporation or its local distributors forservice with pulverulent bodies.

Storage and HandlingValves must be stored in dry, clean and corrosion-freeenvironment with no direct exposure to the sun, leavingvalves open by 10° for prevention of permanent distortionof resilient seats. Refrain from overloading valves andtheir actuators, such as storing them in piles or placingother objects on them.

Mounting on Pipelines1. Valves must be mounted on flanges only after flanges

have been welded to pipes and cooled down to theatmospherical temperature. Otherwise, welding heatmay affect the quality of resilient seats.

2. Edges of welded flanges must be machined for smoothsurface finish so that they may not damage resilientseats during valve mounting. Flange faces must befree from damage or deformation, and be cleaned toremove rust or any other foreign objects so that therewill be no concern of external leakage through valveand flange connections. Gaskets are not required formounting KITZ DJ series butterfly valves.

3. Clean flanges and pipe bores to thoroughly removewelding spatters, scales and other foreign objectswhich may have been left inside.

4. Accurate centering of each couple of upstream anddownstream pipes is essential for trouble-freeoperation of valves mounted between them. Incorrectcentering shown in Fig. 1 must be by all meansavoided.

5. For valve mounting, set jack bolts under the pipes forflat support at the same height, and adjust the flange-to-flange distance so that some 6 mm to 10 mm roommay be allowed beside the both sides of the valvebody.Remember that valves here must be left open only by10° from the fully closed position.

6. Set two bolts into the lower mounting guides of a valveand mount it carefully so that flange faces may notdamage resilient seats. (Fig. 2)

7. Then set another two bolts into the upper mountingguides of a valve, ensuring the correct centeringbetween pipes and the valve.

8. Trially open the valve to check to see if there is nodisturbing contact between the valve disc and theflanges.

9. Remove the jack bolts,set all bolts around thevalve body and tightenthem alternately anddiagonally till the flangescontact the valve body(Fig. 3 and 4). Refer tothe table shown right forrecommended torquevalues.

10.For mounting actuated valves, provide valve supportsto prevent bending of valve necks and reduce valveand pipe vibration.

11.Don’t step on valve necks or valve handwheels.12.Don’t mount valves of DN350 and larger with their

operations upside down.13.Don’t mount butterfly valves directly to check valves or

pumps, which may cause damage to them by the disccontacts.

14.Don’t mount valves to downstream sides of elbows,reducers or regulating valves where fluid velocitychanges. It is recommended to install valves approx-imately 10 times of the valve nominal sizes away fromthem for such cases.

15.Mount valves taking consideration of the effects whichdiscs are given by fluid velocity or pressure chages inthe pipings. Refer to the illustrations. (Fig.5)Contact KITZ Corporation or its local distributors forthe details.

Valve Operation1.Valves equipped with manual operators such as

levers, and handles of gears must be ONLYMANUALLY operated. Application of an excessiveexternal force to operate valves may result inmalfunction of valves and their operators.

2.Ensure to fully open valves before a loop test of thepiping system is carried out with line pressure higherthan the nominal pressure of tested valves. Never useclosed valves in place of blind flanges.

3.When valves need to be dismantled from pipes formaintenance or any other cause, ensure to thoroughlyreleave the line pressure beforehand. Looseningpiping bolts under line pressure causes a danger. Anyresidual f luid left inside the pipeline must becompletely drained.

4.Users should contact KITZ Corporation or its localdistributors for technical advice, when valves shouldbe continuously pressurized while left open by 30° orless.

5.Don't use position indicators to operate valves, oroverload position indicators. This may cause damageto indicators.

6.Ensure to use blind flanges when butterfly valves aremounted at the end of pipelines.

7.Standard actuators are referenced in this catalog foractuated valve operation. Contact KITZ Corporation orits local distributors for mounting optional actuators.

8.Contact KITZ Corporation for service at hopper orpump outlets.

9.Avoid touching gear operators and actuator stopperbolts accidentally.

10.It is recommended to perform periodical inspection for• Making sure of valve opening degree• Checking loosened bolts and leakage at each

connection• Checking vibration and noise

11.Refer to instruction manual for other precautions. Alsorefer to actuator catalogs and instruction manuals foractuated valves.
