Stainless Steel Cryogenic Ball Valves

Features
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.
