Cryogenic Emergency Cut Off Valve

High Performance • Durable • Leak Proof

API 6DASME B16.34ISO 17292CE Certified

Cryogenic Emergency Cut Off Valve by African Valve for industrial flow control.

Cryogenic Emergency Shut Off Valves in Nigeria are designed to isolate liquefied gases and cryogenic fluids at extremely low temperatures. Their emergency shut-off function enables rapid interruption of flow during leaks, fire or system failure, while extended bonnets and cryogenic-compatible sealing help maintain reliable valve operation.

Specific size, pressure, temperature and material combinations should be selected according to the cryogenic medium, operating conditions and project specifications. Reference designs include SS304/SS316 bodies, stainless-steel stems and PTFE sealing, with some

Standards

Applicable requirements depend on the valve design and service. ISO 28921-1 covers industrial isolating valves for low-temperature applications down to -196°C, while BS 6364 is widely referenced for cryogenic valve testing. ASME B16.34 may apply to valve pressure-temperature and pressure-containing requirements, with applicable flange and testing standards determined by the selected construction and project specification.
