Aluminum Butterfly Valves by Projectors

KITZ XJ series aluminum butterfly valves with powder coating featuring a unique style for the neck designs to accommodate various piping designs, piping positings and installation environment.

Features:

Easy valve-to-flange centering:
The light weight of the die-cast aluminum valve body (which is only one third of the weight 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 types of line fluid without risk of corrosion.
Stabilized operating torque:
A pair of stem bearings assembled around the top and bottom stems prevents stem galling and stabilizes the 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 that are provided with ISO 5211 valve mounting flanges.
Prevention of dew condensation (Long neck type):
A long stainless steel neck blocks transfer of fluid heat to the valve operating device, so no insulation is needed on the operating device. Dew condensation is also minimized for gear-operated valves used in cold water service.Rust prevention:The main parts such as the stems, discs, necks, neck connectors, and endplates and small parts such as stopper plates, washers, and boltings are all made of stainless steel for high-grade rust prevention.

S-shaped spherical disc for high sealing performance (patented) :
KITZ's original cross-sectionally S-shaped valve discs with spherical surfaces make evenly tight contact with rubber liners for excellent sealing performance with reduced operating torque. Complete 360°shut-off mechanisms help to extend the service life of rubber liners. (Size:≥2 inches)
