For cleaning purposes the tank is often drained and the water supply has to be isolated to prevent the float valve automatically refilling the tank. By incorporating a normally closed servo-controlled solenoid valve upstream of the float valve, but in the same body, this acts as the shut off to the supply line. This combined valve allows other equipment connected to the same supply to remain in operation and also avoids the unintentional refill of the tank in the event of power failure. These valves have a two chamber, straight through body which can be manufactured with various connections. Coil systems for all common voltage and frequency ranges are available. The valve is rated to insulation class F to ensure electrical operating safety, although an additional integrated protective circuit can also be included. By using high quailty insulation materials, a continous 100% duty cycle is possible. Corrosion of the inner parts of the valve which are exposed to the medium is prevented by using high specification stainless steel. □ Irrigation systems □ Industrial appliances □ Air conditioning Pollution equipment Dish washers Washing machines Water treatments
