Matching Flow Diagrams to Replace an Air Directional Control Valve

Choosing an Air Directional Control Valve

Air-Exhaust Flow Control Valves

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

Air-Exhaust Control 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.

Elbow Air-Exhaust Control Valves with Flow Control

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.

Elbow Air-Exhaust Control Valves

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.

Quiet Air-Exhaust Control 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.

Made-to-Order Air-Operated
Air-Exhaust Control 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.

Electrically Operated Air Directional
Control Valves with Flow Control

Use a single valve to create motion and control the speed of that motion.

Slow-Start Actuated Air-Exhaust Valves

Slow-Start Air-Exhaust Valves for Festo Modular
Compressed Air Filter/Regulator/Lubricators (FRLs)

Also known as Monday-morning valves, these valves slowly introduce pressure to reduce surge damage during start-up.

Slow-Start Air-Exhaust Valves for SMC Modular
Compressed Air Filter/Regulator/Lubricators (FRLs)

Also known as Monday-morning valves, these valves slowly introduce pressure to reduce surge damage during start-up.

Slow-Start Air-Exhaust Valves for
Wilkerson Modular Compressed
Air Filter/Regulator/Lubricators (FRLs)

Also known as Monday-morning valves, these valves slowly introduce pressure to reduce surge damage during start-up.

Slow-Start Air-Exhaust Valves for Norgren Modular
Compressed Air Filter/Regulator/Lubricators (FRLs)

Also known as Monday-morning valves, these valves slowly introduce pressure to reduce surge damage during start-up.

Mufflers

Flow-Control Mufflers

Adjust the flow by turning the screw. Use these mufflers with air-powered tools and cylinders to reduce noise and filter exhaust fumes.

Clog-Resistant Mufflers

Replace your muffler less often—these have a filter design that stays clean longer than porous mufflers.
