Compact Threaded On/Off Valves for Chemicals
For chemical-processing applications in confined areas, these valves have an EPDM seal and a PVC or CPVC body to withstand aggressive and corrosive solutions and a low-profile handle to fit in tight spots.
Full-port valves do not restrict flow.
Standard-port valves 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.

Threaded Flow-Adjustment Valves for Cryogenic Liquid
- 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.
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.

Compact Threaded Flow-Adjustment 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.

Flanged Flow-Adjustment Valves for Chemicals
With seats that can stand up to aggressive and corrosive solutions, these valves are often used in chemical-processing applications. They bolt to flanges for adjusting and regulating flow in flanged pipelines.
Wafer valves must be sandwiched between two flanges; they have tabs or unthreaded holes to help align the valve between the flanges.
Lug valves can be sandwiched between two flanges or bolted directly to a single flange for servicing one end of the pipeline without depressurizing the other side. They have threaded flange holes with a hole pattern that matches ANSI flanges of the same pipe size.
Lockable lever handles have 10 flow-adjustment positions. The handle can be fixed in place with a padlock (not included).
Wheel handles open and close with multiple turns, providing fully adjustable flow.

Easy-to-Install Threaded Check Valves for Harsh Chemicals
To reduce installation time and allow for maintenance without detaching pipe connections, these valves have union fittings. The plastic body and fluoroelastomer seal provide excellent chemical resistance. Valves open to allow flow in one direction and close when flow stops or reverses.
PVC and CPVC valves come with unthreaded socket-connect female fittings in addition to the threaded NPT female fittings.
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.

Vacuum-Breaking Valves for Chemicals
A plastic body withstands pH neutralizing, cleaning, and plating solutions containing sodium hydroxide, methyl ethyl ketone, and other harsh chemicals. Also known as vacuum breakers, these valves have vents that open when pressure drops to relieve vacuum conditions and prevent backward suction from drawing liquid into upstream piping.

Made of PVC, these orifices have excellent resistance to a wide range of corrosive chemicals. Also known as flow restrictors and precision orifice valves, they are used to throttle, vent, bleed, or regulate the flow of liquids and gases. They automatically adjust to changing inlet pressure to maintain consistent outlet flow.

Pressure-Relief Valves for Cryogenic Applications
- For Use With: Liquid Carbon Dioxide, Liquid Nitrogen, Liquid Oxygen
- Temperature Range: -320° to 165° F
Cleaned and bagged to meet CGA G-4.1 for oxygen service and other high-purity applications, these valves are built to withstand the extreme cold of liquid carbon dioxide, liquid nitrogen, and liquid oxygen. They begin opening at the set pressure and fully open at about 10% over the set pressure. Valves begin closing as pressure drops and fully close when the system pressure is restored below the set pressure. Set pressure is not adjustable.
Valves are not intended for direct contact with cryogenic liquids. Risers (sold separately) are required to convert cryogenic liquids into gases before they contact the valve. 3/8 NPT valve requires a 1/2 NPT × 3/8 NPT bushing when using a riser.
Adapters (sold separately) convert the valve relief-port connection from UNEF female threads to NPT female threads.

Extended-Life Pressure-Regulating Valves for Cryogenic Liquids
- For Use With: Liquid Argon, Liquid Carbon Dioxide, Liquid Nitrogen, Liquid Oxygen
- Temperature Range: -320° to 150° F
For a longer service life than standard valves for cryogenic liquids, these have a durable bronze body. All are cleaned and bagged for oxygen service and other high-purity applications. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves are designed to withstand the extreme cold of liquid argon, liquid carbon dioxide, liquid nitrogen, and liquid oxygen. They have an internal strainer to trap debris.

Pressure-Regulating Valves for Cryogenic Liquids
- For Use With: Liquid Argon, Liquid Carbon Dioxide, Liquid Nitrogen, Liquid Oxygen
- Temperature Range: -320° to 150° F
These valves can withstand the extreme cold of liquid argon, liquid carbon dioxide, liquid nitrogen, and liquid oxygen. All are cleaned and bagged for oxygen service and other high-purity applications. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range.
