Product Detail
Cryogenic gate valve
Main features: Low temperature valve is designed with extended bonnet, which can protect stem packing and stuffing box area to avoid the effect from low temperature that causing the stem packing lost its elasticity. Extended area is also convenient for insulation protection. Valves are suitable for Ethylene, LNG plants, air separation plant, Petrochemical gas separation plant, PSA oxygen plant, etc.
