Ultra-low temperature valves
ZIPSON 305C, 3-PC Cryogenic Ball Valve
Tongue & Groove
body and end connection
Zipson’s 305C type cryogenic ball valve was designed with tongue & groove body/ end connection for better sealing as the valves are operated under cryogenic and higher working pressure. This safer valve design helps to protect not only the users but also the environment.
-196°C Harshest Working Condition
As an ISO 9001 certified supplier, Zipson follow the orders of the best design for the cryogenic working condition.
At the extremely low working temperature, the operation torque increase significantly. Zipson use 17-4 stem for the cryogenic valve to keep from stem twist.
The sealing area between body & end caps, Zipson use tongue & groove design for better sealing ability to prevent from outer leakage.
There will always need a pressure release hole on the upstream side of the ball.
Body & end caps quality investment casting
Stem extension according to Shell SPE 77/200
Tongue & groove body seal design for better sealing
Heavy duty design
1500 psi (1/4″~2″)/ 1000 psi (2-1/2″~4″)
with ISO 5211 direct mounting pad
High performance adjustable stem packing
Blow-out proof stem design
Ball pressure release hole on upstream side
As an ISO 9001 certified supplier, Zipson is capable of manufacturing the cryogenic valves with best design and quality, for the harshest working temperature, -196°CZipson’s 305C cryogenic ball valves are designed for various media, such as liquid nitrogen, Helium, CO2 and other liquid gases. They are suitable for warehouse logistic, medical, pharmaceutical, transportation industries. All the valve casting parts are produced in Zipson’s investment casting foundry in Taiwan with precision and accuracy. Our 305C valves are compliant with ASME B16.34 standard and are safe for users and the environment.With tongue & groove body/ end connection design and TFM1600 seals, the 305C type has better sealing ability and can avoid external leakage in both low pressure and high pressure working conditions. We also add the spring-loaded stem (self-adjusting stem packing) in our design. It can make the sealing ability better, and also extend the service life of our 305C type greatly. The cryogenic extended bonnet follows SHELL SPE 77 200-2013 standard.
