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.
Watersavers supply a range of WRAS approved solenoid shut off valves in the UK 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, or electric water valves as there are also known, 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.
Solenoid Valves are used for a variety of applications and are a key element of any flow control system.
A solenoid valve is essentially an electromechanical controlled valve. It features a tiny solenoid which is an electric coil containing a movable ferromagnetic core located at the centre. This is called a plunger. In it’s resting position it closes off an orifice. A small electric current is then passed through the coil creating a magnetic field in the electric water valve.
The magnetic field pushes the plunger and the plunger is pulled toward the centre of the coil so that the orifice becomes open. This is essentially the basic principle for the electric water valve that is used to open and close solenoid valves.
Electric water valves are amongst the most used components in gas and liquid circuits. The number of applications is almost endless. Some examples of the use of solenoid valves include heating systems, compressed air technology, industrial automation, swimming pools, sprinkler systems, washing machines, dental equipment, car wash systems and irrigation systems.
