Cryogenic Ball Valve

Cryogenic Ball Valve Manufacturer in Nigeria use quarter-turn operation to provide rapid opening and closing, with the ball, seats, stem and sealing components selected for the required low-temperature service. Depending on the design, floating or trunnion-mounted configurations and extended bonnet arrangements can be used for different pressure, size and installation requirements

Cryogenic Ball Valve Features

Quarter-turn operation - Enables quick valve opening and closing.
Cryogenic construction - Materials are selected for the specified low-temperature service.
Reliable isolation - Provides effective shut-off when correctly sized and specified.
Extended bonnet options - Keeps stem sealing components away from the cold zone where required.
Cryogenic seating - Seat materials are selected according to temperature and medium.
Full or reduced bore - Bore configuration can be selected according to flow requirements.
Cavity-pressure management - Suitable seat designs can address pressure from trapped cryogenic fluid.
Manual or actuated operation - Operation can be selected according to the installation.
