To prevent accidental start-up, these valves can be locked in their off position with a padlock. Also known as 3-way and 3/2 valves, they create one action, such as extending a cylinder. Valves direct airflow from the inlet to your equipment and exhaust return airflow to create motion. They're normally closed to block airflow until actuated. Return actuation is by hand, so they stay actuated and return to their starting position only when you move the actuator again. In the off position, they exhaust air pressure from the system, allowing equipment to reset so the action can be repeated.

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

Because they require a key to operate, you can limit who is able to adjust these valves. Also known as 3-way and 3/2 valves, they create one action, such as extending a cylinder. Valves direct airflow from the inlet to your equipment and exhaust return airflow to create motion. They're normally closed to block airflow until actuated.

The push buttons that operate these valves are separate from the logic unit, allowing you to position them away from machinery. Since both hands are required to simultaneously press the buttons, they protect workers from accidental machinery start-up. Also known as 3-way and 3/2 valves, they create one action, such as extending a cylinder. Valves direct airflow from the inlet to your equipment and exhaust return airflow to create motion. They're normally closed to block airflow until actuated. Return actuation is by spring, so valves return to their starting position as soon as you release the actuator. In the off position, they exhaust air from the system, allowing equipment to reset so the action can be repeated.

Note: Valve is sold as a complete unit, consisting of one logic unit and two signal valves. Port size given is for the logic unit. Signal valve port size is 1/8 NPT female.

Also known as 3-way and 3/2 valves, they create one action, such as extending a cylinder. Valves direct airflow from the inlet to your equipment and exhaust return airflow to create motion. They can be installed normally open to allow airflow until actuated, or installed to block airflow and until actuated. Return actuation is by spring, so valves return to their starting position as soon as you release the actuator. In the off position, they exhaust air pressure from the system, allowing equipment to reset so the action can be repeated.

These valves create one action, such as extending a cylinder. Apply voltage to the electrical connection to actuate. Also known as 3-way and 3/2 valves, they direct airflow from the inlet to your equipment and exhaust return airflow to create motion. In the off position, they exhaust air from the system, allowing equipment to reset so the action can be repeated.

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

Valves with spring return actuation go back to their original position when voltage is removed. Valves with electric (solenoid) return actuation go back to their original position when voltage is moved from the first solenoid to the second solenoid.

NPTF (Dryseal) threads are compatible with NPT threads.

Manifold-mount valves plug into a manifold (sold separately) to create multiple actions from a single pressure input. Manifolds with multiple exhaust ports have one set of inlet and exhaust ports on each side, so they can be strung together in a series. When using a single manifold, cover the ports on the side you are not using with plugs (sold separately).

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.

A simple automation solution that requires no programming, these valves are activated when an object, such as a box rolling on a conveyor, pushes the actuator. Also known as 3-way and 3/2 valves, they create one action, such as extending a cylinder. Valves direct airflow from the inlet to your equipment and exhaust return airflow to create motion. They're normally closed to normally block airflow, and remain closed until actuated. Return actuation is by spring, so they go back to their starting position as soon as the actuator is released. In the off position, they exhaust air pressure from the system, allowing equipment to reset so the action can be repeated.

Valves with a one-direction actuator are activated by objects from one side.

Valves with a two-direction actuator are activated by objects from both sides.

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.

Also known as 3-way or 3/2 valves, these valves create one action, such as extending a cylinder. Use your foot to operate them, leaving your hands free to perform other tasks. Valves direct airflow from the inlet to your equipment and exhaust return airflow to create motion. They're normally closed to normally block airflow, and remain closed until actuated. Return actuation is by spring, so they go back to their original position as soon as you release the actuator. In the off position, they exhaust air pressure from the system, allowing equipment to reset so the action can be repeated.
