Wirquin Topy Filling Valve

Wirquin Topy Filling Valve


The Wirquin Toppy Filling Valve is designed to silently fill and maintain the water level in WC cisterns and are available in a bottom entry version only. An adjustable float is connected to a short lever arm which is in turn connected to the valve body which either rises or falls depending on whether the cistern is emptying or filling. When the tank empties, the float falls and the arm which is connected to a Piston retracts from the diaphragm washer/seat of the valve causing the water to flow in. Conversely when the float rises; the piston slowly closes against the diaphragm/seat and shuts off the water supply.
