• Worcester Cryogenic Ball Valve

  • FloSource is proud to announce a stocking program for the Worcester Controls Cryogenic Ball Valve line.  The Worcester Cryogenic Ball Valve line includes stainless and brass valves for cryogenic service up to -425 F.  The C44, C4, and C51 valves are many features listed below

    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 one-piece and two-piece, assembledinside-the-body stems are safe from blowout and are supported with Polyfill® thrustwashers. Zero Leak Packing – Belleville live-loaded TFE packing rings and stem centering followers assure zero leakage through the toughest, highcycle applications.

    Effective Bonnet Extensions – The stem extensions 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 -425°F. Valves Designed for Automation – Approximately 40% of cryogenic installations require fail-safe operation or automatic on/off control. Worcester Controls has the pneumatic and electronic, computercompatible controls for your installation. Valves Designed for Fire Safety – A Series 94 double-graphite, stemsealed 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.
