Also known as 4-way and 4/2 valves, these valves 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. Valves without an exhaust connection exhaust air to the atmosphere.
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.

Two-Action Air Directional Control Valves with Exhausting Shut-Off

In the off position, these valves exhaust all air pressure, allowing equipment to return to the neutral position. Also known as 4-way and 4/3 exhaust-center valves, they create two actions, such as extracting 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 hand, so valves stay actuated and return to their original position only when you move the actuator again.

These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. Also known as 4-way and 4/3 closed-center valves, they create two actions, such as extracting 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 hand, so valves stay actuated and return to their original position only when you move the actuator again.

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.

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.
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.

Control six different outputs from a single source of airflow. These valves have one inlet port and six outlet ports. Push in and rotate the dial to move between outlet ports and send airflow to a different output. Also known as 3-way 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. Return actuation is by hand, so the chosen output remains actuated until you move the dial to another position. Air pressure exhausts to the atmosphere once a new position is selected.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

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. They help meet OSHA 29 CFR 1910.147 procedures for the control of energy sources that could injure workers.

Simultaneous Two-Action Air Directional Control Valves
![](/prerenderstable/mvPRE/contents/gfx/imagecache/336/3368k13-@halfx_1678482350.png?ver=imagenotfound)
Also known as 4-way and 5/3 pressure center valves, these valves create two actions at the same time, such as extending two single-acting cylinders at once. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion.
Valves with spring return actuation go back 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.

Safety-Lockout Air On/Off Valves

A padlock (not included) locks the handle of these valves in the shut-off position. When valves are closed, the exhaust port vents air pressure so you can disconnect air tools safely. They meet OSHA lockout requirements to maintain safety and control in a compressed air system.
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.
Valves that comply with OSHA 29 CFR 1910.147 meet standards for the control of energy sources that could injure workers.

- Valve Type: Ball
- For Use With: Beverage, Food
- Seal Material : PTFE Plastic
To maintain sanitary standards in food and beverage applications, these valves have sanitary quick-clamp connections and polished internal surfaces for easy cleaning. The three-piece bolted body comes apart for access to internal components without unthreading pipe connections and removing the valve from your line. They have a ball-valve design that provides higher flow rates than other air-driven valves. All operate on compressed air to automatically start and stop flow faster than motor-driven valves. You must control the air to the actuator using either an electric pilot valve or a manual on/off valve (not included). These valves do not require a minimum pressure drop between the inlet and the outlet for operation. All are full port, so they do not restrict flow.
Body is 316 stainless steel for excellent corrosion resistance. The actuator is directly mounted to the valve body to minimize movement and reduce wear. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. The manual override allows you to operate the valve during power outages.
Single-acting actuators only require air pressure to open the valve; they automatically spring closed when the air turns off. These valves are normally closed unless actuated. Double-acting actuators require air pressure to open and close the valve. Once actuated, these valves remain actuated until air pressure is applied, so they do not have a valve starting position.
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.
