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

Change outlet pressure without using a gauge—turn the dial to adjust the outlet pressure in 5 or 10 psi increments.

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.

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.

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

The most basic option for air and inert gas applications.

Use these valves with liquid argon, liquid nitrogen, and liquid oxygen.

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

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

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.

Solder these valves to copper tubing for a permanent, leak-tight connection.
