Cryogenic Gate Valve Manufacturer in Europe – Valvesonly Europe

Valvesonly Europe is a specialized Cryogenic Gate Valve Manufacturer in Europe, with manufacturing facilities in Germany and Italy. Our cryogenic gate valves are designed for applications involving LNG, liquid nitrogen, oxygen, argon, hydrogen, and ethylene. Built to operate safely at temperatures down to –196°C, these valves feature an extended bonnet and extended body construction to ensure the stem packing remains above the frost line, protecting it from extreme cold and ice formation.

Function & Working

Cryogenic gate valves provide linear shut-off in pipelines carrying liquefied gases at cryogenic temperatures. A wedge-shaped gate moves perpendicular to the flow to ensure tight sealing and full-bore opening with minimal pressure drop. The extended bonnet and body design ensure the gland packing and stem sealing elements are kept away from direct cryogenic exposure, enhancing operational reliability.

Testing & Quality Validation

All cryogenic gate valves are tested as per BS 6364 and ISO 28921 standards to guarantee performance and safety.

• Cryogenic proof testing at –196°C in liquid nitrogen bath

• Helium leak detection for micro-sealing integrity

• Hydrostatic pressure test for body and bonnet strength

• Seat leakage tests at both ambient and cryogenic conditions

• Fugitive emission tests to ISO 15848-1 / API 641 for low-emission performance
