These valves create one action, such as extending a cylinder. Also known as 3/2 or pilot valves, they use an air signal to actuate, so they're good for environments where electrical use may be dangerous. They direct airflow from an inlet to your equipment and exhaust return airflow to create motion. In the off position, they exhaust air pressure from the system, allowing equipment to reset so the action can be repeated.

Normally closed valves normally block airflow, and remain closed until actuated. Valves that are both normally closed and normally open can be installed to normally block airflow, or to normally allow flow and remain open until actuated.

Valves with spring return actuation go back to their starting position as soon as the air supply is removed. Valves with air pilot return actuation go back to their starting position when the air supply is moved from the first air pilot to the second air pilot.

Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Also known as blocking valves, these valves are activated by an air signal to turn equipment on and off. They allow airflow when an air signal is applied to the air pilot. When the air supply is removed, the valve closes, trapping air in the system.

Valves with push-to-connect ports are for use with plastic or soft metal tubing. Insert tubing into the port.

Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.

Protect air-powered equipment in emergency shut-off situations—when system pressure drops, the air pilot signal stops and these valves automatically close to stop cylinder motion, even at a mid-stroke. They control the speed of air-powered equipment by adjusting the volume of airflow. A pressure-release button allows you to exhaust any trapped air pressure from the system after shut down. Install them in pairs on cylinder exhaust ports, and use tee connectors (not included) to direct exhaust air from the cylinder to the air pilot of the opposite valve, and to connect valves to a directional control valve. The elbow shape allows you to mount them directly to cylinder ports, eliminating additional tubing or piping between the cylinder and valve for better control and consistency than inline valves.

Two direction valves control airflow as it enters (meter in) and exits (meter out) equipment, and are often used to control the extension and retraction speed of an air cylinder at the same time. One direction valves control flow as air exits the cylinder (meter out) and moves from the inlet to the outlet.

Valves with push-to-connect ports are for use with plastic or soft metal tubing. Insert tubing into the port.

Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

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. A muffler reduces exhaust noise. Also known as quick exhaust valves.

To Order: Specify minimum pressure and maximum pressure from the ranges listed. The difference between the minimum pressure and maximum pressure must be at least 10 psi, but no more than 30 psi.

These valves convert a continuous steam of air into a series of rapid pulses, reducing air consumption by up to 50% and improving performance in air blowing applications such as cleaning and drying.

Valves with air-pilot actuation activate when they receive an air signal.

Normally closed valves normally block flow, remaining closed until actuated.

Flow coefficient (Cv) is the amount of airflow in standard cubic feet per minute (scfm) a valve can deliver to a cylinder.
