Solenoid On/Off Valves with Flow Adjustment

For Use With: Water
Seal Material: EPDM Rubber

Turn the knob to adjust how much these valves will open or close when actuated. They are often used in irrigation and landscaping applications. All operate on electricity to automatically start and stop flow.

These valves require a minimum pressure drop between the inlet and the outlet for operation; the upstream pressure must be greater than the downstream pressure. The actuator is directly mounted to the valve body to minimize movement and reduce wear.

Normally closed valves are closed unless actuated. Normally open valves are open unless actuated.

Washdown-Resistant Electrically Operated Air Directional Control Valves

IP69K, these valves withstand high-pressure, high-temperature washdowns. Their smooth design also keeps out dust, dirt, and contaminants, so they're easy to keep clean. Apply voltage to the electrical connection to actuate. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion.

3-way valves create one action, such as extending a cylinder. 4-way valves create two actions, such as extending and then retracting a double-acting cylinder.

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.

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.

Valves with two exhaust ports allow you to independently control the speed of two different actions. Connect a flow control valve to each exhaust port.

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