The most basic option for air and inert gas applications.

Attach a pressure gauge to the 1/4 NPT female port on these valves.

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.

To gradually relieve pressure in lines for diesel fuel, fuel oil, gasoline, and kerosene, these valves begin opening at the set pressure and fully open at about 10% over the set pressure.

Use this valve in light duty water systems with garden hose thread (GHT) connections.

Valves have a brass body and NPT connections.

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.

Our smallest pressure-regulating valve.

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 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.

It's like getting four regulators in one—each comes with four springs so you can change between regulating pressure ranges of 2-30, 10-50, 30-90, and 100-180 psi.

These valves have a vented relief port to exhaust discharge directly.

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