Two-Speed Two-Action Air Directional Control Valves
Often used to extend and then retract a cylinder at different speeds, these valves 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. Also known as 4-way and 5/2 valves.
Valves with spring return actuation return to their original position as soon as you release the actuator.
Valves with hand return actuation stay actuated and return to their original position only when you move the actuator again.
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.

Two-Speed Two-Action Air Directional
Control Valves with Exhausting Shut-Off
In the off position, these valves exhaust all air pressure, allowing the equipment to return to the neutral position. 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. Also known as 4-way and 5/3 exhaust center valves.
Valves with hand return actuation stay actuated and go back to their original position only when you move the actuator again.
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.

Single-Action Air Directional Control Valves
Manually control these valves by pushing or turning the actuator. Also known as 3-way or 3/2 valves, they create one action, such as extending a cylinder. They direct airflow from the 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 block airflow until actuated. Valves that are both normally closed and normally open can be installed to block airflow, or allow air to flow until actuated.
Valves with hand return actuation stay actuated and go back to their starting position only when you move the actuator again. Valves with spring return actuation go back to their starting position as soon as you release the actuator.
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.

Fast-Acting Panel-Mount Threaded On/Off Valves
Open and close these valves with the flip of the toggle switch. Commonly used for equipment testing and gas sampling, they have threads and a hex nut below the handle for installation in instrument panels.
Manual-return valves remain open or closed when the toggle is moved into position.
Spring-return valves automatically close when the toggle is released.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Gradual On/Off Valves with
Quick-Clamp Fittings for High Vacuum
Also known as vacuum isolation valves, these block flow so you can install and remove gauges from your system. They can also be used to add or vent gases in high-vacuum systems. Valves gradually open and close with multiple turns of the wheel handle to prevent system damage from suddenly starting and stopping flow. They connect to another quick-clamp fitting with a clamp and a ring (sold separately). All have a nonrising stem that stays in the same position whether the valve is open or closed. Body is 304 stainless steel for good corrosion resistance.
