The most basic option for air and inert gas applications.

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

Commonly used with high-volume blowers, compressors, and air-powered conveyors, these valves quickly relieve a large amount of air in systems with a pipe size of 2 or greater. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

Commonly used with high-volume blowers, compressors, and air-powered conveyors, these valves quickly relieve a large amount of air in systems with a pipe size of 2 or greater.

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

These valves meet ASME Code Section VIII for use with water pressure vessels.

Also known as T & P valves, these open when water temperature reaches 210° F or at the set pressure.

For use with low-pressure steam-heating boilers requiring pressure relief at 15 psi, these valves meet ASME Code Section IV.

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

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

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

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.

These valves are often used in hydraulic and lubrication systems.

Design a valve specifically for your process media and set pressure. Choose from a valve for air, inert gas, water, hydraulic oil, fuel oil, gasoline, or diesel fuel and a set pressure.

These valves are made of corrosion-resistant materials for use in wet conditions and harsh environments.

For excellent corrosion resistance in wet conditions and harsh environments, these valves have no metal parts.

An internal wire brush traps air bubbles and discharges them through the top relief port while allowing inline flow from the inlet to the outlet.

Eliminate air pockets in your drinking water system with these valves. They meet NSF/ANSI 61, which designates them as safe to use with drinking water.

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.

A muffler reduces exhaust noise. Valves allow airflow into your equipment and then 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.

Choose the pressure range you need. When these valves receive an air signal, they quickly dump exhaust air to the atmosphere without routing it back through a directional control valve to speed up the movement of equipment. They're often used with air compressors that require continuous operation. Also known as quick exhaust valves.

A 316 stainless steel housing allows these regulators to withstand corrosive environments in the semiconductor, marine, chemical, instrumentation, and paper industries.

Adjust and maintain the pressure of your compressed air.

An internal check valve permits reverse flow, so these regulators work with double-acting cylinders.

Adjust and maintain the pressure of your compressed air.

A lower profile than our other compressed air regulators makes these regulators a better fit in tight spots.

Adjust and maintain the pressure of your compressed air.

With a greater flow capacity than our standard precision compressed air regulators, use these regulators to adjust and maintain air pressure in sensitive high-flow applications where constant, consistent pressure is important.

At ±0.1% accuracy, use these regulators in sensitive applications where constant, consistent pressure is important.

Mount these regulators to a 35 mm DIN rail or a wall with one of the two included brackets.

Keep an eye on the output pressure in high-flow applications—these regulators have a display so you can monitor your application locally.

View and control output pressure remotely and at the source.

Also known as Monday-morning valves, these valves slowly introduce pressure to reduce surge damage during start-up.

Also known as Monday-morning valves, these valves slowly introduce pressure to reduce surge damage during start-up.

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

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