Compact Solenoid On/Off Valves for Coolant
- For Use With: Ethylene Glycol
- Seal Material: Fluoroelastomer Rubber
- Specifications Met: See table
Reduce your pipeline footprint with these low-profile valves that are about half the size of standard valves for coolant. They operate on electricity to automatically start and stop flow.
Valves are normally closed unless actuated. They don’t require a minimum pressure drop between the inlet and outlet for operation. The actuator is directly mounted to the valve body to minimize movement and reduce wear.
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.

Two-Speed Two-Action Electrically Operated 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. Also known as 4-way and 5/2 valves, they actuate when voltage is applied to the electrical connection. 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 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.
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 Electrically Operated Air
Directional Control Valves with Full Shut-Off
These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. 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. Apply voltage to the electrical connection to actuate. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Also known as 4-way and 5/3 closed center valves.
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.

Electrically Operated Air Directional Control Valves with Flow Control
Create motion and control the speed of that motion with a single valve. Also known as 4-way valves, these valves create two actions, such as extending and retracting a double-acting cylinder. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion, and adjust the volume of air exiting an air cylinder (meter out) to control speed. Apply voltage to the electrical connection to actuate.
5/3 (closed center valves) close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. 5/3 (pressure center) valves create two actions at the same time, such as extending two single-acting cylinders at once.
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 moves from the first solenoid to the second solenoid.
