How does irrigation valve work

To close the valve, turn the solenoid clockwise until the valve closes. This is the method that many prefer because most times when you open the manual bleed screw, it causes water to leak out into the valve box. If the valve is left on for any period of time, it can start filling the valve box with water.

So the next time your sprinkler system is not working correctly, and you need to apply water, try operating the zone valve manually. There are 2 simple methods to open the valve manually: 1. Open the Manual Bleed Screw The first way to open this valve is to open the manual bleed screw. Turn the Solenoid The second way to open the valve is to grasp the solenoid the black cylinder with the wires attached to it and turn it approximately one-quarter turn counter-clockwise until the valve opens.

Solenoid valve for irrigation. A water irrigation solenoid valve is an electrically controlled valve to regulate the flow of water.

By applying a voltage over the coil, the valve opens and the liquid can flow through. Solenoid valves are also called electromagnetic valve , water valve , electric valve or electro valve. Similarly, what does the sprinkler solenoid do? The solenoid controls a spring-loaded metal piston that opens or closes the water port passing through the valve. Irrigation zone valves come in many shapes and configurations, including models that integrate an anti-siphon device.

If your solenoid is bad, the water pressure in the sprinkler chamber will not be changed and the valve will fail to open. Turn off the water supply. Open the solenoid housing and inspect the plunger.
