PBM Cryogenic Ball Valves
PBM cryogenic valves have a unique design that provides superior performance through cooling and 
heating cycles. The valves have been shown to meet leakage criteria per MSS SP-134.
An extended bonnet with an upper set of live loaded stem packings. As metal shrinks, it keeps pressure on seals as temperature goes through cooling and heating cycles. The vented ball allows explosive gas expansion to vent upstream.
Cryogenic valves are optimally oriented with the stem 90° from the horizontal plane. PBM cryogenic valves are capable of operating with the stem oriented as low as 45° above the horizontal plane.
