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

Thicker walls and a 304 stainless steel seal make these valves tougher than brass pressure-regulating valves.

Prevent changes to your pressure setting—these valves come set at a nonadjustable outlet pressure.

Excellent performance at low pressures.

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.

For a longer service life than cast iron valves, these have a durable bronze body.

For use with acetylene, hydrogen, methane, propane, or propylene gas.

These valves meet NSF/ANSI 61 for use in drinking water systems.

Designed for oxygen service and other high-purity applications, these valves can withstand the extreme cold of liquid argon, liquid carbon dioxide, liquid nitrogen, and liquid oxygen.

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.

These valves meet ASME Code Section I for use with steam power boilers requiring pressure relief above 15 psi.

Choose these valves for small steam-heating boilers requiring pressure relief between 5 psi and 12 psi.

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.

These valves meet ASME Code Section VIII for use with water pressure vessels.

Alter the set pressure to suit your application.

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

A finely threaded adjustment screw lets you make precise set pressure adjustments.

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

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

Integral shutoff valves isolate flow for inline maintenance, and a top-entry cover provides easy access to internal components.

Attach these valves with NPT connections to threaded pipe.
