Cryogenic Ball Valve is mainly applied to various fire control systems station road, turn on or shut off the pipeline medium. Suitable medium: water, steam and other non-corrosive media.compared to the other valve products ,the charactery of Cryogenic Ball Valve is high temperature and high pressure,the unique self-sealing design, the higher the pressure, the more reliable seal.
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.
