Fast-Acting Threaded On/Off Valves
Push a button or flip a toggle switch to start or stop flow. Often used in testing and sampling, these valves are useful when you need to dispense a small amount of liquid.
Nickel-plated brass valves resist corrosion better than plain brass valves.
Push-button valves automatically open or close when you take your finger off the button. They’re ideal for intermittent use and applications where you want to monitor flow closely to avoid spills. The button is colored to make it easy to tell different valves apart. Normally open valves close when you push their button. Normally closed valves open when you push their button.
Valves with an exhaust port release extra air or liquid when they close. When these valves open, the exhaust port closes.
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.

Fast-Acting Panel-Mount Threaded On/Off Valves

Start or stop flow with the flip of a toggle switch or the push of a button. These valves are often used in testing and sampling applications where you need to dispense a small amount of liquid. They fit through a cutout, so the body of the valve stays safe inside your instrumentation panel.
Nickel-plated brass valves resist corrosion better than plain brass valves. Spring-return valves automatically close when you release the toggle or push button. They’re ideal for intermittent use and precise flow control to prevent spills.
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.

Swivel Threaded On/Off Valves
Make connections from any direction—the body of these valves swivels 360° for easy installation. Often used in testing and sampling applications, they quickly open and close with a toggle or button.
Push-button valves open when you press the button. When released, the button springs back and automatically stops flow. They’re ideal for intermittent use and controlling flow to avoid spills.

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. 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 threaded exhaust connection type allow you to control the speed of each action by attaching a flow control valve to each exhaust port.
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-Hand Two-Action Air Directional Control Valves

Since both hands are required to simultaneously press the buttons, these valves protect workers from accidental machinery start-up. Also known as 4-way and 4/2 valves, they create two actions, such as extending and then retracting a double-acting cylinder. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Return actuation is by spring, so valves return to their original position as soon as you release the actuator.

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. Valves without an exhaust connection exhaust air to the atmosphere.
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.

Two-Hand Single-Action Air Directional Control Valves

Since both hands are required to simultaneously press the buttons, these valves protect workers from accidental machinery start-up. Also known as 2-hand control 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 until actuated. Return actuation is by spring, so valves return to their starting position as soon as you release the actuator. These valves actuate any 3 or 4-way air piloted spring return power valve or small single-acting cylinders. In the off position, they exhaust air pressure from the system to the atmosphere, 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.

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