A BS 6364 gate valve is a highly specialized linear-motion isolation valve engineered, manufactured, and impact-tested to ensure cryogenic structural integrity down to -196 °C. Conforming strictly to the British Standard BS 6364, this valve features an extended bonnet column that positions the stem packing gland away from the ultra-cold process fluid, creating a vapor barrier that prevents the packing from freezing and losing its seal. Fabricated from low-temperature austenitic stainless steels or specialized bronze, the internal wedge provides an unobstructed, full-bore flow path with negligible pressure drop when raised. These high-integrity cryogenic gate valves are mandatory engineering requirements for liquid nitrogen transport, liquefied natural gas processing facilities, and aerospace fueling manifolds. Sourcing managers and high-pressure pipeline contractors can eliminate sub-zero brittle fracture risks and protect downstream pumps by importing certified BS 6364 gate valves directly from premier manufacturers in China via our B2B commercial platform.
