Abstract

The float controlled valve is of the king having a valve housing in which is located a flexible diaphragm carrying a valve member arranged to engage a valve seating to close the valve. The diaphragm divides the housing into an inlet chamber and a back pressure chamber to communication with each other whereby the pressurised supply acts on both sides of the diaphragm and provides a resultant force urging the valve member towards the valve seating. A float operated pilot valve controls an outlet port in the back pressure chamber, whereby the back pressure can be relieved to permit the valve member to move away from its seating, wherein the float operated pilot valve has an actuating lever which is pivoted at one end to the valve housing and is adapted to carry a float at its other end, the lever arm being shaped so that it extends from its float carrying end up one side of the valve housing and over the top of the valve housing to its pivotal connection at the opposite side of the valve housing.
