These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure.

Excellent performance at low pressures.

Valves have a brass body and NPT connections.

Often used for oxygen service and other high-purity applications, these valves are cleaned and bagged to meet CGA G-4.1 standards to prevent contamination.

Withstand inlet pressures up to 3,500 psi.

These valves automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure.

Reduce contaminants in gases used in research sample systems, emission monitoring systems, chromatography, and other high-purity applications. These valves have a 316 stainless steel and brass body with a smooth finish to reduce dust collection and internal components designed to protect the seal and diaphragm from contamination.

Commonly used in TIG welding where gas flow/coverage is a concern.

Designed to reduce contaminants in high-purity applications using hydrogen and methane gas, these valves have a stainless steel and brass body with a smooth finish to reduce dust collection and internal components designed to protect the seal and diaphragm from contamination.

Install these valves directly in gas distribution pipelines.

Choose from valves for liquid argon, liquid nitrogen, liquid carbon dioxide, or liquid oxygen tanks.

Body is brass or nickel-plated brass. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

Change set pressure to suit your application—this valve includes four interchangeable color-coded springs with different set pressure ranges.

Our only valves that meet ASME Code Section VIII for use with cryogenic pressure vessels. They are for use with argon, carbon dioxide, helium, hydrogen, methane, nitrogen, and oxygen.

Change set pressure without guesswork—the adjustment screw is marked in 25 psi increments for making pressure adjustments without a gauge.

To gradually relieve pressure in lines for diesel fuel, fuel oil, gasoline, and kerosene, these valves begin opening at the set pressure and fully open at about 10% over the set pressure.

For precise control over your vacuum level, these valves have ±0.1% accuracy.

A lower profile than our other compressed air regulators makes these regulators a better fit in tight spots.

A clear polyurethane bowl makes these filter/regulators chemical resistant for use with synthetic compressor oils and cleaning fluids and allows you to see inside to monitor contents.

Commonly used with irrigation systems and laboratory equipment, these valves have NPT connections.
