The most basic option for air and inert gas applications.

These valves have a bronze body for durability and a long service life. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

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.

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.

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

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

Alter the set pressure to suit your application.

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.

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.

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.

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.

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.

Install these discs within the bolt circle of ANSI Class 150 flanges.

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.

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.

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

Set a specific pressure and these valves will maintain it.
