Main features: Low-temperature valve is designed with an extended bonnet, which can protect the stem packing and stuffing box area to avoid the effect of low temperature that causes the stem packing to lose its elasticity. An extended area is also convenient for insulation protection. Valves are suitable for Ethylene, LNG plants, air separation plant, Petrochemical gas separation plant, PSA oxygen plants, etc.
