    Choose the right valve for your application by matching the actions you'll power to our flow diagrams.

    Key-Operated Two-Speed Two-Action Air Directional Control Valves

    Because they require a key to operate, you can limit who is able to adjust these valves. Often used to extend and then retract a cylinder at different speeds, they create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by hand, so they stay actuated and return to their original position only when you move the actuator again. Also known as 4-way and 5/2 valves.
    Flow Coefficient (Cv)—Flow coefficient (Cv) indicates how much airflow can pass through a valve.

    Key-Operated Single-Action Air Directional Control Valves

    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 fail 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 to the atmosphere, allowing equipment to reset so the action can be repeated.

    Key-Operated Air-Release Valves for Water

    Image of Product. Front orientation. Air Vent Valves. Key-Operated Air-Release Valves for Water.
    Turn the key to manually release air from radiators, heaters, and other hot water equipment. These valves have a vented relief port that exhausts discharge directly. Body is nickel-plated brass for good corrosion resistance.
