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.

Valves have a brass body.

Our smallest pressure-regulating valve.

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

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

Designed for nitrogen gas purging in air conditioning, refrigeration, and plumbing systems.

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

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.

Instead of exhausting discharge directly, these discs have a threaded relief port for attaching a drain line to direct discharge away from your work environment.

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