Practically, the pressure reducing solenoid control valves are hydraulic control valves which using electricity for doing the opening-closing upfunction remotely and automatically. A desired exit pressure value can be adjusted easily with the pilot valves placed on the pressure reducing solenoid control valves. A control device that can give electrical signals with the help of PLC control units or time relays, controls the pressure reducing solenoid control valves.

The solenoid valves used on the control valve can be 3/2 or 2/2 way valves for different applications.
The solenoid control valves can be selected optionally, normally closed up(N.C.) or normally opened up (N.O.).
The standart voltage value of the solenoid control valves is 24 Volt AC. But, there is an opportunity for selecting different voltage values like 9 Volt DC latching or 12 Volt DC bobbins.
A desired exit pressure value can be adjusted easily with the pilot valve placed on the pressure reducing solenoid control valve.
With adding pilot valves that will be mounted on the main valve which provide different pressure, flowrate and level control to the system, the solenoid control valves can be used in many different applications.
Mount the valve according to the arrow placed on the valve that shows the flow direction.
Mounting isolation valves (gate, butterfly or ball etc.) at the entrance direction for shutting-off the water in the line are recommended to ease the maintenance of the valve.
For the valve’s efficient working it is recommended to use an air relief valve before the valve.
Evacuate the water in the valve’s actuator to the atmosphere to prevent freezing in winter.
After mounting the main valve to the network, mount the solenoid valve’s electrical connector to the control device that you will use.
Select truely the cable’s diameter which used for electrical connection between the control device and the solenoid control valve, in the guidence of the solenoid valve’s electrical specification and the distance.
The control device’s voltage value must be same with the solenoid valve’s voltage value.
Adjust the valve’s exit pressure value with the adjust screw of the pressure reducing pilot valve as shown with 2. The pressure value increases when you turn the adjust screw clockwise. If you turn it counter clockwise, the pressure value reduces.
Clean the filter (strainer) as shown with 5 according to the water pollution degree.
