A solenoid operated pilot valve utilizes an offset pilot opening and a lever arm to provide a mechanical advantage to multiply the opening force of the solenoid, thereby allowing the solenoid size to be reduced. The lever arm used to position the pilot valving member is mechanically positioned via a solenoid driven plunger in one embodiment, and is positioned by magnetic force alone in an alternative, plungerless embodiment. The lever arm pivots via a fixed fulcrum point, a profiled fulcrum providing continuously variable mechanical advantage, or a stepp...


1. A pilot operated water valve, comprising: a valve body having an inlet, an outlet, and a main valving chamber defined therebetween, the valve body further defining a bypass channel in fluid communication with the outlet;a main valving chamber body operably coupled to the valve body to enclose the main valving chamber, the main valving chamber body forming a pilot valve opening therein to provide fluid communication between the main valving chamber and the bypass channel;a main valving member positioned in the main valving chamber and operable to contr...
