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.

These valves are commonly used with pumps in low-pressure water systems.

Cleaned and bagged 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.

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

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.

Often used for pressure-vessel testing and other high-pressure applications, these valves can handle at least seven times the outlet pressure of standard tank-mount pressure-regulating valves.

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.

Flowmeters let you see the gas flow rate from a distance.

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.

Install these valves directly in gas distribution pipelines.

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

Also known as fusible plugs, these discs have a metal core that melts at a set temperature to exhaust discharge directly.

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