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

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

To maintain contaminant-free standards in clean room environments, these valves come cleaned and bagged to Fed. Std. Class 100 and ISO Class 5 clean room standards and have a 316 stainless steel body with a smooth finish to resist dust collection.

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

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.

Valves have a brass body.

Withstand inlet pressures up to 3,500 psi.

Our smallest pressure-regulating valve.

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.

Use these valves in pipelines.

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

Commonly used with high-volume blowers, compressors, and air-powered conveyors, these valves quickly relieve a large amount of air in systems with a pipe size of 2 or greater. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

Commonly used with high-volume blowers, compressors, and air-powered conveyors, these valves quickly relieve a large amount of air in systems with a pipe size of 2 or greater.

For corrosion resistance in wet conditions and harsh environments, these valves have a 303 stainless steel body. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

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.

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.

For a longer service life than brass vacuum-regulating valves, these are made of bronze for strength and durability.
