Practically, the solenoid control valves are hydraulic control valves which using electricity for doing the opening-closing up function remotely and automatically. A control device that can give electrical signals with the help of PLC control units or time relays, controls the solenoid control valves.
1. The solenoid valves used on the control valve can be 3/2 or 2/2 way valves for different applications.
2. The solenoid control valves can be selected optionally, normally closed up(N.C.) or normally opened up (N.O.).
3. 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.
VALVE OPEN
When the user sends an electric signal to the 3/2 solenoid valve on the solenoid control valve by means of a control device, the solenoid valve closes the "P" port, preventing the line pressure from entering the solenoid valve. The pressurized water in the valve actuator passes through port "C" of the solenoid valve and reaches port "V" and the pressurized water in the valve actuator is evacuated to the atmosphere, opening the main valve fully.
VALVE CLOSED
When the user stops the electric signal from the control device, P "port switches to the open position and the" V "port switches to the off position by changing the solenoid core position in the solenoid valve. Thus, the line pressure solenoid valve reaches the port "C" from the port "P" and fills the actuator of the valve, thereby ensuring that the main valve is completely sealed.

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 solenoid valve’s electrical specification and the distance.
The control device’s voltage value must be same with the solenoid valve’s voltage value.
Turn the ball valve as shown with 4 to the desired position to open and close up the main valve.
Clean the filter (strainer) as shown with 5 according to the water pollution degree.
