Cryogenic valves are kept in a natural closed position to keep cryogenic gasses or other mediums secure and safely contained. A cryogenic valve is generally designed to react to high pressure which pushes the valve into the open position to allow the gas or other media to flow readily through.
What is a Cryogenic Ball Valve?
Cryogenic ball valve specifically designed for use on liquid gases such as nitrogen and oxygen. It offers high-performance, shutoff valves for intermittent and continuous flow applications with temperatures to -196℃.
Design Features of Cryogenic Ball Valve
Bonnet extension with live-loaded stem seal.
Body cavity relief hole in ball to prevent over-pressure due to thermal expansion.
Blow out proof stem.
Engineered material components to ensure low thermal stress.
What is a Cryogenic Globe Valve?
Cryogenic globe valve is often referred to as an open/close valve or a shut-off valve to control the opening/closing of flow paths in pipes and is used to regulate the flow in gas and liquids installations. Globe valves can be operated manually using a hand wheel, by a motor, or by an external drive, which can be pneumatic, electric, or magnetic. A globe valve is utilized to achieve either a full-flow or complete shut-off scenario, with the cone resting flat on the valve seat to interrupt the flow of media.
Design Features of Cryogenic Globe Valve
Extended bonnets with sufficient gas column length.
Flexible wedges with CoCr alloy seating faces for cryogenic service.
Cleaning: All cryogenic valves are thoroughly degreased and cleaned and pipe ends are sealed to prevent contamination.
