Solenoid Shut off Valves

A range of WRAS approved solenoid shut off valves for isolating cold and or hot water supplies in buildings in accordance with BREEAM guidelines.

These WRAS approved Normally Closed brass solenoid shut off valves are typically controlled using PIR Occupancy Switches to shut off the water supply or supplies when the building or part of the building eg toilet area is unoccupied thus preventing potential loss of water and or water damage due to burst or leaking fittings, vandalism etc. Other uses include restricting the amount of water used in a building or controlling the volume of water used by operatives, machines or processes such as cleaning, rinsing irrigation.These sanitary shut off valves are available in sizes from 1/2″ to 2″ BSP.

Other applications call for control by a manual STOP switch or by automatic control using a 24 hour or 7 day time switch. For example many premises such as dentist’s surgeries have a solenoid shut off valve fitted to the main water inlet and controlled by a time switch so that the water supply is switched off during the night and at times when the surgery is closed. Hence a water leak which could potentially cause catastrophic damage can be avoided.
Other applications include manual or automatic control of water to holiday lets and homes – giving peace of mind.

1)  Select the size according to the existing pipe or line size – usually 1/2″ through 2″ BSP. The valves have BSP female threads so you may need
‘male irons’ to convert to copper compression.
2)  The majority of the valves that we sell are Normally Closed or powered to open which means that they will ‘fail safe’ in the event of a power loss.
Certain applications may require that water can still be drawn in the event of power failure. Consider this carefully before choosing.
3)  Specify the correct coil voltage whether it be 230v AC, 110v AC, 24v AC or DC, 12v DC or other. This is important!
4)  Our SVM range of solenoid shut off valves are ‘pilot operated’ utilising the mains water pressure in order to open and close. They require typically a minimum differential pressure of 0.35 BAR (about 12 feet) in order to operate. If you have a tank fed application please contact sales for details of a suitable valve to operate down to 0 BAR.
