SVM range of WRAS approved, Normally Closed (power to open), pilot operated, brass solenoid shut off valves. They may be controlled by an on/off switch, a time switch or by a PIR switch for BREEAM credits. Standard 230/240v AC, other voltage options available.
Prices from £42.72 each
Plastic DIN solenoid valve connectors. Rectangular type are suitable for our 1/2″, 3/4″ and 1″ WRAS approved solenoid valves, the square DIN connectors are suitable for 1.25″ sizes and larger. Priced at £2.75 each
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 (aka electric water valves) are available in sizes from 1/2″ to 2″ BSP.
Electric Water Valve
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.
HOW DO I CHOOSE A SOLENOID WATER SHUT OFF VALVE?
1) Select the size of the electric water valve 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 electric water 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.

Electric Water Main Shut Off Valve
Our UK Winters can affect many homes, causing water pipes in houses to burst causing a large amount of water damage which invariably can cause an insurance claim during the winter period for the escape of water due to burst water pipes.
This can be avoided with the use of one of our Electric Water Main Shut Off Valves.
During these cold months, always check pipes around the property for bulges or frost covering. A pipe which is frozen is not always visible. Turning off your mains water supply before leaving the house unoccupied for a winter break could stop wider damage caused by a burst water pipe.
The main water valve in a property controls the water flow and in case of an emergency, everyone should be able to access their mains water valve (also known as a stopcock).
Brass stopcocks have usually been the electric water main shut off valve for a home’s mains water supply however they are not always located in the most accessible places and can be quite difficult to turn off in an emergency due to limescale.
