Valve is an essential part of the irrigation sprinkler system. The main components of sprinkler valves are the diaphram, solenoid, springs, and various gaskets or O-rings. The solenoid, an electric cylinder, is a crucial part of an automatic valve. The solenoid receives electric message from the sprinkler system controller, and in turn controls the movement of the diaphram. Manual irrigation valves don’t require a solenoid.

The diaphram is the rubber plug inside the valve, responsible for opening or shutting off the flow of water. Behind the diaphragm is a wire spring. Some irrigation valves have a jar-top lid; in others, the lid may be held in place with screws. Many valve designs feature a bleed screw, which can be tightened or loosened to manually control the flow of water to the valve.

If one of the lawn sprinkler valves needs repair, it;s usually not necessary to replace the entire valve. The valve can be disassembled, and the components separately replaced. Major manufactures of sprinkler valves also make replacements parts, and it’s often easier to replace the parts than to cut the entire valve from the pipe.

  1. I have a Hunter system and just this year my zone #4 comes on for exactly 2 minutes then stops. My controler shows that there is still 18 min left and continues to count down the little pic on the screen shows that the heads should be up. Is this a failing solenoid valve?
