Speciality Valve – Cryogenic Valves for LNG, Hydrogen, and Industrial Gas Applications

Speciality Valve is a leading Cryogenic Valve Manufacturer and Supplier in India, supplying valves designed to perform reliably at extreme temperatures down to –196 °C. Our cryogenic valves are built with extended bonnets, precision trims, and low-temperature sealing systems to ensure safe, leak-free performance in LNG, hydrogen, and industrial gas applications.

Function & Working

Cryogenic valves are built to withstand sub-zero conditions where conventional valves fail due to material brittleness and seal leakage. The extended bonnet design keeps the stem packing away from the cryogenic fluid, preventing frost formation and ensuring reliable operation. Combined with carefully selected materials and sealing elements, our valves guarantee smooth flow control and bubble-tight shut-off in demanding low-temperature environments.
