This Cryogenic Gate Valve is designed for low-temperature applications involving LPG and LNG. Featuring an extended stem for safe operation at cryogenic conditions, it is manufactured to API 602 standards with a forged ASTM A182 F304 stainless steel body. With a 3/4 inch size and Class 150 LB pressure rating, this valve ensures reliable shutoff and durability in cold service environments, making it ideal for cryogenic processing, storage, and transport systems.

Cryogenic Gate Valves are engineered and manufactured in strict compliance with international standards such as API 602, ASME B16.34, and DIN 3202 or their equivalents. These valves feature a compact yet exceptionally sturdy design suitable for high-pressure and high-temperature applications, including cryogenic service.
An optional solid CoCr alloy wedge provides low friction and extended service life. Packing rings are pre-compressed to 4000 psi to ensure a high-integrity seal. In welded bonnet designs, the bonnet is threaded and torqued to a specific engineered value, with the body-bonnet joint strength-welded for double protection against leakage.
The fully guided wedge reduces wear on seating surfaces. Optional features include double packing, leak-off connections, live-loading, and a packing blowout for easy removal of worn packing.
