Cryogenic, Hydrogen & LNG Valves

Cryogenic gas relief valves, non-ASME – specifically designed for vapor line safety relief applications and cryogenic liquid containers. Tamper resistant; colour coded labels clearly identify pressure setting range.

Extended bonnet valves for use on cryogenic tanks. Special features include spring loaded packing.

Cryogenic ½” combination pressure builder/economizer for bulk vessels. CB504 series regulators maintain the pressure of cryogenic liquid within bulk vessels combining the pressure building and economizer function in one unit with ½” NPT inlet and outlet.

Cryogenic ¼” combination pressure builder/economizer. High and low pressure builders/economizers are the same compact size – ideal for installations with limited space.

Cryogenic economizers designed to be used as pressure reducing valves to automatically maintain a constant inlet or back pressure – normally closed at pressures below its set point and open at pressures above its set point. Ideal for Nitrogen, Oxygen, Argon and other cryogenic cylinder applications.

Extended stem valves for use as a trycock valve or hose drain valve on cryogenic tanks.  Can also be used for other cold gas applications requiring extended stem valves as LNG fueling.

Cryogenic liquid cylinder regulator – controls the pressure from the gas use line or the discharge of any liquid cylinder with a flow capacity at least double that of the cylinder vaporization coil. For use with oxygen, nitrogen, argon, or carbon dioxide liquid cylinders.

Cryogenic ½” pressure builder regulators primarily designed to maintain the pressure in cryogenic containers. May also be used as a line regulator for cryogenic lines and cold gas lines. Requires less field repair because of the diaphragm design (squeezed vs twisted) and is easier to service with an allen wrench, versus a large crescent wrench.

Cryogenic gas relief valves, ASME – designed for oxygen and other industrial gases and for cryogenic service in the vapour space. Apply on piping systems, liquid cylinders or mini-bulk cryogenic containers where an ASME relief valve is required.

Cryogenic pressure builder regulators primarily designed to maintain pressure on cryogenic liquid within cryogenic containers. May also be used in cryogenic lines, vaporizer and converter applications. High and low pressure regulators are the same compact size – ideal for installations with limited space.
