Stainless Steel Cryogenic Ball Valve

Product Description
Cryogenic Ball Valve -> Stainless Steel Cryogenic Ball Valve
Applications such as liquefied natural gas and other low temperature fluids, present special extreme temperature valve functionality challenges. Valves designed for cryogenic services, are specially prepared and designed to overcome these challenges. Appropriate component materials such as 304SS (CF8) and 316SS (CF8M) are normally used for body and trim, offering superior impact strength, and excellent corrosion resistance and heat loss properties. An extended bonnet and gas column design is also normally adopted to provide thermal insulation at the stem seal and stem packing area. At sufficient length, this design feature places the functionality of the stem seal in the vapor zone of the liquid media providing safe and continuous valve operation. A variety of body, trim, seat, and seal materials are available for use in cryogenic service. Customer specified options, such as body cavity vent hole, special extension lengths, and materials are also available upon request.

Features of Stainless Steel Cryogenic Ball Valves:
1. Positive ball cavity relief to prevent dangerous overpressure due to thermal expansion.
2. Pressure safe stem assembled inside the body for blowout prevention.
3. Zero leak packing incorporating bellville spring live loaded packing assures zero leakage and high cycle life.
4. Effective bonnet extension conforms to industry standards for wall thickness and lengths reducing heat transfer and frost free packing.
5. High performance/low thermal stress design of valve parts assure tight shutoff, zero body leakage and low torque through large thermal excursions from ambient to -150F.
