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.

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.

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.

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

The most basic option for air and inert gas applications.

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.

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.

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

Choose these valves for small steam-heating boilers requiring pressure relief between 5 psi and 12 psi.

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