Valves

We offer a variety of options to suit your specific needs. Solenoid valves open and close electronically, ideal for automated watering schedules. Check valves prevent unwanted backflow within the system. Isolation valves allow you to shut off water supply to specific zones for maintenance or repairs. Keep everything protected with our durable valve boxes, providing easy access to underground valves while shielding them from the elements. Shop now and discover the perfect valves to optimise water flow and ensure a well-functioning irrigation system!

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.
