Aluminum Butterfly Valves XJ Series

KITZ XJ Series aluminum butterfly valves : Featured with unique style of the neck designs(U.S.P. No.6676109), for accommodation of various piping designs, piping positions and installation environments.

Two neck designs for your choice : Long neck type, short neck type are available for versatile applications.

Easy valve-to-flange centering : Light weight of die-cast aluminum valve body (which is only one-thirds of KITZ's conventional cast iron butterfly valves) eases valve-to-flange centering work on mounting valves on pipelines.

Wide range of service applications : Austenitic stainless steel discs and EPDM rubber seats can handle many different kinds of line fluid without concern of corrosion. Short Neck

Stabilized operating torque : A pair of stem bearing assembled around the top and bottom stems prevents stem galling, and stabilizes valve operating torque for smooth and trouble-free disc rotation.

On-the-spot actuator assembly : The actuator mounting pads of all necks are designed in conformity with ISO 5211 requirements for direct on-site mounting of actuators which are provided with ISO 5211 valve mounting flanges.

Long Neck

Prevention of dew condensation (Long neck type) : A long stainless steel neck blocks transfer of the fluid heat to a valve operating device, which thus needs no insulation on the operating device. Dew condensation is minimized also in case of gear operated valves on cold water service.

Rust prevention : Main parts such as stems, discs, necks, neck connectors and endplates, and small parts such as stopper plates, washers and boltings are all made of stainless steel for highly graded rust prevention.

S-shape spherical disc for high sealing performance (patented) : KITZ's original cross-sectionally S-shaped valve discs with spherical surface evenly make tight contact with rubber liners for excellent sealing performance with reduced operating torque. Thorough 360゜shut-off mechanism helps extend service life of rubber liners. (Size 2inch and over.)

Reinforcing back-ribs to minimize valve operating problems such as distortion, skidding and exfoliation of rubber liners caused by line pressure load and friction with metal discs.

■Dew Condensation Test

■Corrosion Resistance Level This table indicates general corrosion resistance level of the materials of discs and rubber liners used for KITZ XJ Series butterfly valves against typical line fluids. The data is based on the laboratory test finding on material test specimens (not valve component test specimens) under constantly controlled test conditions, and thus each data may be subject to variation, depending on actual valve service conditions in the field. Please contact KITZ Corporation for technical advice, if service conditions are extra-ordinarily severe, or you have any doubt about corrosion resistance level of valves onsite. Also please contact KITZ Corporation when valves are used for hot water service. = Excellent = Good = Less recommended = Not recommended Materials Fluid Acetic acid(10%) Air Ammonia(anhydrous liquid)

Pipes Recommended for Use of Butterfly Valves When butterfly valves are being opened, move of discs may be interrupted by pipe internals. Where butterfly valves are connected with welded pipe flanges shown in the right illustration, use of pipes given in the right table is recommended. Valve-to-flange centering work must be always accurately done on valve mounting on pipelines.

2 Edges of welded flanges must be machined for smooth

surface finish so that they may not damage resilient seats during valve mounting. Flange faces must be free from damage or deformation, and be cleaned to remove rust or any other foreign objects so that there will be no concern of external leakage through valve and flange connections. Gaskets are not required for mounting KITZ XJ series butterfly valves.

stream pipes is essential for trouble-free operation of valves mounted between them. Incorrect centering shown in Fig.1 must be by all means avoided. Fig.1

10 For mounting actuated valves, provide valve supports to (a)

prevent bending of valve necks and reduce valve and pipe vibration. 11 Don't step on valve necks or valve hand-wheels. 12 Don‘t mount butterfly valves directly to check valves or

pumps, which may cause damage to them by the disc contacts. 13 Don‘t mount valves to downstream sides of elbows, redu(b)
