Cryogenic Gate Valve

High Performance • Durable • Leak Proof

API 6DASME B16.34ISO 17292CE Certified

Forged steel cryogenic gate valves with extended bonnet design for LNG and low-temperature service.

Cryogenic Gate Valve Manufacturer in Algeria provide isolation solutions for pipelines and process systems handling fluids at extremely low temperatures. Gate valves are primarily used for full-flow isolation rather than continuous throttling, with cryogenic designs incorporating extended bonnets, low-temperature materials and specialized seating arrangements. Suitable designs are available for services approaching −196°C, subject to the valve construction and qualification.

Materials

Body material- ASTM A351 CF8 / CF8M / CF3M; ASTM A182 F304 / F316 and trim materials may include F304, F316, CF8, CF8M. Seat, packing and fastener materials are selected according to minimum temperature, pressure, medium and service conditions.

Applications in Algeria

Cryogenic gate valves are particularly relevant to Algeria’s LNG infrastructure at Skikda and Arzew/Bethioua, where low-temperature isolation is required in liquefaction, storage and transfer systems. They are also applicable to industrial gas facilities, refrigerated LPG storage, cryogenic transfer lines and petrochemical operations. African Valve offers cryogenic gate valve solutions for these applications, configured according to the required temperature, pressure and service conditions.

Standards

Depending on design, applicable standards can include BS 6364, ISO 28921-1, API 600, API 603 and ASME B16.34, with ASME B16.5 or B16.25 applying to relevant connections. African Valve's range follows applicable API, ASME and ISO standards, with the exact certification confirmed against the supplied valve and project specification.
