Solenoid Flow-Adjustment Valves

Also known as proportional solenoid valves, these adjust and regulate flow based on the intensity of the electrical signal into the valve. All are controlled with PWM signal. Valves are fail closed unless actuated. They require a minimum pressure drop between the inlet and outlet for operation; the upstream pressure must be 7 psi greater than the downstream pressure. The actuator is directly mounted to the valve body to minimize movement and reduce wear. Valves are IP65 rated to resist splashing water and dust. Add a cable plug for DIN connection. To program these valves, use the programmable logic controller (PLC). It has a DIN plug connector and can operate 4-20mA inputs.

Flow Coefficient (Cv)—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.

Compact Solenoid Flow-Adjustment Valves

Available in smaller pipe sizes than other solenoid flow-adjustment valves, these are often used with gas controllers and analytical instrumentation. They adjust and regulate flow based on the intensity of the electrical signal into the valve and are often integrated into PLC systems for automatic control over the valve position based on system conditions. They are fail closed unless actuated. Valves don’t require a pressure drop for operation. The actuator is directly mounted to the valve body to minimize movement and reduce wear.

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) Flow Pattern—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) Flow Pattern—5/3 (pressure center) valves create two actions at the same time, such as extending two single-acting cylinders at once.

Spring Return—Valves with spring return actuation go back to their original position when voltage is removed.

Solenoid Return—Valves with solenoid return actuation go back to their original position when voltage is moved from the first solenoid to the second solenoid.

Flow Coefficient (Cv)—Flow coefficient (Cv) indicates how much airflow can pass through a valve.
