GCV-L series deep-cooling regulating valves are commonly used in LNG, air separation, chemical and other industries. Special seal design for low temperature, better performance and longer life.

A cryogenic extension bonnet can be matched with cryogenic bellows internal parts to realize zero leakage. The standard actuator interface can be adapted to a variety of models of pneumatic or electric actuators. A variety of internal structures are available, including linear, isobaric and perforated cages.
