Abstract
A solenoid valve is provided that comprises a valve body having an inlet and an outlet, and a movable member for moving a valve element away from a valve seat to open the valve. The moveable member engages and moves the valve element away from the seat to an open position when the solenoid is actuated. When the solenoid is not actuated, a biasing spring moves the moveable member to disengage from the valve element, which returns to a closed position. The moveable member does not transfer any impact force to the valve element on closure of the valve member, so that the valve may be operated a significant number of cycles without failure.
