FAQ's

What does a solenoid valve do in an irrigation system?

A solenoid valve acts like a switch for water flow in irrigation. When activated by an irrigation controller, it opens an internal passage, allowing water to flow to a specific zone (sprinklers, drip system) and closes when shut off by the controller, stopping water flow.

What is a solenoid valve diaphragm used for?

In a solenoid valve, the diaphragm is a crucial component that acts as a barrier between the control mechanism (electrical coil) and the fluid being controlled (water, air, etc.). It has two main functions:

Sealing: The diaphragm separates the pressurised fluid from the electrical components of the valve. This prevents water damage to the coil and ensures a safe electrical operation.

Controlling Flow: The diaphragm moves based on the energising or de-energising of the solenoid coil. When energised, the coil creates a magnetic field that pulls the diaphragm open, allowing fluid to flow through the valve. Conversely, when de-energised, the magnetic field collapses, and a spring or fluid pressure pushes the diaphragm back to its closed position, stopping the flow.

How long do valve boxes last?

With proper care, many years.
