Valves for Cryogenic Liquid
- Valve Type: Globe
- For Use With: Liquid Argon, Liquid Carbon Dioxide, Liquid Nitrogen
- Specifications Met: CGA G-4.1
Often used with portable cryogenic cylinders, these valves are a third of the height of other valves for cryogenic liquid. They are designed to withstand the extreme cold of liquid argon, liquid carbon dioxide, and liquid nitrogen; all are cleaned and bagged to meet CGA G-4.1 standards for oxygen service. These valves gradually open and close with multiple turns of the wheel handle to adjust and regulate flow. They have a nonrising stem that stays in the same position whether the valve is open or closed.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

- Valve Type: Globe
- For Use With: Liquid Argon, Liquid Carbon Dioxide, Liquid Nitrogen
- Seal Material: Glass-Filled PTFE Plastic
- Specifications Met: CGA G-4.1
Designed to withstand the extreme cold of liquid argon, liquid carbon dioxide, and liquid nitrogen, these valves are cleaned and bagged to meet CGA G-4.1 standards for oxygen service. They gradually open and close with multiple turns of the wheel handle to adjust and regulate flow. All have a rising stem that lifts as the valve opens and lowers as the valve closes to provide a visual indication of whether flow is on or off.

Attach gauges or sensors to these valves so you can remove them for maintenance and calibration without depressurizing your line. Also known as block and bleed valves, turn the handles to block both upstream and downstream flow, drain the liquid trapped in the valve through the bleed port, and then remove your instrument from the gauge port. Often used in chemical-processing lines, these valves have a PEEK seal and a corrosion-resistant 316 stainless steel body. All are standard port, so they slightly restrict flow.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

For extra gripping power and a strong seal, the Yor-Lok fittings on these valves have two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. These valves have a PTFE seal and a corrosion-resistant 316 stainless steel body that can stand up to aggressive and corrosive solutions in chemical-processing applications. All are standard port, so they slightly restrict flow.
Solenoid On/Off Valves for Cryogenic Liquids
Built to withstand the extreme cold of liquid nitrogen and liquid oxygen, these valves are cleaned and bagged for high-purity applications. They operate on electricity to automatically start and stop flow.
All valves are normally closed unless actuated. The actuator is directly mounted to the valve body to minimize movement and reduce wear.
Zero pressure drop valves don’t require a minimum pressure drop between the inlet and outlet for operation. Pressure drop assisted valves require a minimum pressure drop between the inlet and the outlet for operation; the upstream pressure must be greater than the downstream pressure.
NEMA 2 valves resist light splashing water and dust.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

High-Flow Flanged Air-Driven On/Off Valves
- Valve Type: Ball
- For Use With: Oil, Air, Natural Gas, Propane, Butane, Argon, Diesel Fuel, Ethylene Glycol, Fuel Oil, Gasoline, Helium, Kerosene, Liquid Argon, Liquid Nitrogen, Neon, Steam, Xenon, Krypton
- Seal Material : PTFE Plastic
- Specifications Met: ANSI B16.34
Their ball-valve design allows these valves to handle three times the flow of other flanged valves. They operate on compressed air to automatically start and stop flow faster actuation than motor-driven valves. You must control the air to the actuator using either the included electric pilot valve or a manual on/off valve (not included). These valves don’t require a minimum pressure drop between the inlet and outlet for operation. All are full port, so they do not restrict flow.
The actuator is secured to the valve body with a bracket for easy disassembly, maintenance, and repair. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. The manual override allows you to operate the valve during power outages.
Single-acting actuators only require air pressure to open the valve; they automatically spring closed when the air turns off. These valves are normally closed unless actuated. Double-acting actuators require air pressure to open and close the valve. Once actuated, these valves remain actuated until air pressure is applied to close them, so they do not have a valve starting position.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
