Low temperature gate valve
The Low Temperature Gate Valve features an extended bonnet design that protects stem sealing components from cryogenic temperatures. Manufactured from premium low-temperature resistant materials, it offers excellent sealing performance, low operating torque, long service life, and compliance with international standards for LNG, LPG, and industrial gas applications.
Low Temperature Gate Valve
Low Temperature Gate Valves are specially engineered for cryogenic and ultra-low temperature services down to -196°C. Designed according to API 600 and BS 6364 standards, these valves ensure tight shut-off, operational reliability, and maximum safety under severe operating conditions.
The extended bonnet structure minimizes heat transfer and protects packing materials from low temperatures. Available in multiple pressure classes, materials, and connection types, these valves are ideal for LNG terminals, gas processing facilities, petrochemical plants, and cryogenic storage systems.
As a professional valve manufacturer, we provide complete OEM and ODM solutions for global distributors, EPC contractors, and industrial projects.
Our products are manufactured under strict quality management systems and comply with international valve industry standards.
