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.

For corrosion resistance in wet conditions and harsh environments, these valves have a 303 stainless steel body. 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.

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.

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 commonly used with pumps in low-pressure water 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.

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.

A finely threaded adjustment screw lets you make precise set pressure adjustments.

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.

Turn the key to manually vent radiators and heaters.

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.

Use this valve with oil, diesel fuel, gasoline, and kerosene.

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.

Often used in testing and sampling applications, these valves open and close with the push of a button. They are designed for installation in tight spots. Use with water, oil, and air.

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.
