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.

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.

Body is brass or nickel-plated brass. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

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. 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.

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.

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.

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

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

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.

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

These valves are often used in hydraulic and lubrication systems.

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.

Use these valves in pipelines.

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

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.

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

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.

Our only air-release valves for steam, these seal shut when steam enters the valve to prevent system contents from escaping through the relief port.

Push a button or flip a toggle switch to start or stop flow.

Flip the toggle to quickly turn these valves on and off. All have threads and a hex nut below the handle for installation in instrument panels. For extra gripping power and a strong seal, they have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. These valves are for use with water, oil, air, and inert gas.
