Worcester controls has the quality solution for tough applications involving all types of cryogens; oxygen, hydrogen, methane, ammonia, nitrogen, flourine, LNG and deuterium. Our complete line of cryogenic valves backed by years of successful field experience, incorporates superior technology and design. This means automatic or manual control of cryogenic fluids with no contamination, no fluid degradation and no waste while assuring safety to human life, property and the environment. The wrong specs here can turn an inferior valve into a time bomb. Tough applications demand Worcester Controls'special service cryogenic valves. Here's why: 

 
Positive Ball Cavity Relief: An upstream relief hole in the ball prevents dangerous overpressure due to thermal expansion. On extended stem valves through 2", a one-piece stem with alignment pin assures proper orientation of the ball. 

Pressure Safe Stem: Both single piece and two-piece, assembled-inside-the-body stems are safe from blowout and are supported inside the body with Polyfill thrustwashers.

Zero Leak Packing: Belleville live loaded TFE packing rings and stem centering followers assure zero leakage through the toughest, high cycle applications. 

Effective Bonnet Extensions: The stem exten- sions of Worcester controls'cryogenic valves conform to standard industrial practices. That means wall thickness and lengths that keep heat transfer down, the packing frost free, operational torques low, and actuators solidly supported.

High Performance/Low Thermal Stress: The special "part compatibility" design of valve parts, Polyfill seats and body seals assure tight shutoff, zero body leakage and low torque through large thermal excursions from ambient to -4250F.

Valves Designed for Automation: Approximately 40% of cryogenic installations require fail-safe operation or automatic on-off or throttling control. Worcester controls has the pneumatic and electronic, computer compatible controls for your installation.

Valves Designed for Fire Safety: A Series 94 fire tight version of our cryogenic valve is available through the Custom Products Department. These valves are especially effective in hydrogen and liquefied natural gas systems.
