Cryogenic Gate Valve

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. 

Key Features

• Extended bonnet for cryogenic service

• Rising-stem or OS&Y configurations, depending on design

• Wedge or other gate arrangements selected for the application

• Austenitic stainless-steel and other cryogenic-compatible materials

• Flanged or welded ends  RF, RTJ and butt-weld connections can be provided according to piping requirements. 

• Manual, gear, pneumatic or electric operation depending on size and application

• Cryogenic testing where specified by the applicable standard

Technical Specifications

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.
