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

Alter the set pressure to suit your application.

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

For a low-pressure seal around plastic and soft metal tubing, these valves have push-to-connect fittings.

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.

With a three-port design, these valves allow inline flow from the inlet to the outlet during normal conditions and divert flow through the relief port in overpressure conditions. They are often used with feed pumps for fertilizers and bleach.

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.

A cast iron body absorbs vibration from pressure changes to reduce wear and noise in your pipeline.

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

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

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.

Often used on dispensers, humidifiers, and fountains, these valves have a 316 stainless steel body that can stand up to deionized water and corrosive conditions.

Valves have a brass body and NPT connections.

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.

Our smallest pressure-regulating valve.

Valves have a brass body.

Regulate pressure in air and inert gas systems from your instrument panel—these valves have threads below the adjustment knob and come with a panel-mount nut.

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

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.

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

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.

A plastic body and fluoroelastomer seal stand up to harsh chemicals.

A 316 stainless steel body provides exceptional corrosion resistance in wet conditions and harsh environments.

Control steam line pressure with ±1 psi accuracy.

Compression fittings bite down on hard metal and plastic tubing for a tighter seal than push-to-connect fittings.

These valves meet NSF/ANSI 61 for use in drinking water systems.

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

Regulate air, gas, and liquid pressure on food, beverage, and pharmaceutical lines with these valves—they’re 3-A certified to meet sanitary design standards.

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.

For a longer service than cast iron valves, these have a durable bronze body and a 303 stainless steel seal.

Use these valves in pipelines.

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.

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

Regulate vacuum levels from your instrument panel with these valves that have threads below the adjustment handle and a panel-mount nut.

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

To set the pressure, unscrew the cap and turn the adjusting screw.

The pressure setting on these valves cannot be adjusted while they are installed.

When input pressure varies, use these valves to maintain a consistent pressure.

Quickly dump exhaust air to the atmosphere without routing it back through a directional control valve to speed up the movement of equipment. Also known as quick exhaust valves.

Control the flow of exhaust air while also regulating the exhaust air speed. These valves dump exhaust air to the atmosphere without routing it back through a directional control valve. The 90° elbow shape allows you to install them in tight spaces. Also known as quick exhaust valves.

Install these valves in the exhaust ports of air directional control valves to control exhaust air speed without needing access to your cylinder.
