Cryogenic gate valves generally favor to valves with working temperatures below – 196 degree C. it is widely used in LPG, LNG and another low temperature industry. Valves designed for cryogenic services, are mainly prepared and designed to overcome these challenges. Right part materials such as 316SS and 304SS are largely used for trim and body, providing best impact strength, and remarkable corrosion resistance and heat loss features. An extended bonnet column design is also generally adopted to offer thermal insulation at the steam seal and stem packing place. A range of body, seat, trim, and seat materials are accessible for use in cryogenic service. Customer specific choices, such as unique extension lengths, body cavity vent hole, and materials are also accessible upon request.
Extended bonnet with ample gas column span, generally specified by customers, are supplied for all control devices to keep stem packing at best distance away from the chill liquid to remain work.
Plug disc with CoCr seating alloy faces for cryogenic services.
Cleaning: All cryogenic gate valves are fully worked and cleaned and pipe finishes are sealed to stop contamination.
Drive model: electric, manual, gear drive and pneumatic
