SKU N/A Category


Buy WRAS approved Solenoid Valves in a variety of sizes. Choose your required size using the drop down menu.

We offer a range of water leak detection isolating solenoid valves which are fail-safe, normally closed valves – meaning it is closed in an unpowered state. In an emergency situation, it is possible to manually override this and open the valve without power.

Please note: A minimum operating pressure of 0.35 bar is required. 

For large quantities, help with installation or specification, contact us to discuss contract pricing and credit accounts.
