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

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

Turn the key to manually vent radiators and heaters.

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.

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.

With a 316 stainless steel body for exceptional corrosion resistance, these valves are often used in wet conditions and harsh environments. 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.

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

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

These valves meet ASME Code Section I for use with steam power boilers requiring pressure relief above 15 psi.

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.

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.

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

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 often used with catalysts, pH buffers, and electroplating solutions.

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.

Quickly vent exhaust air to the atmosphere or divert it to another place in your system to speed up the movement of equipment. 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.

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

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.

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

Set a specific pressure and these valves will maintain it.
