Abstract
A valve is provided that includes a housing having an inlet, an outlet, and a valve seat therebetween. The valve includes a valve member movable towards the valve seat towards engagement with a stop, and away from the valve seat when the solenoid is energized. The valve member has an opening in which a valve element is received. A spring urges the valve member and valve element towards the valve seat, and a solenoid moves the valve member away from the valve seat. The spring biases the valve member to a closed position, in which the valve element engages the valve seat, and the valve member engages a stop that prevents the valve member from impacting against the valve element that is seated against the valve seat. The solenoid when energized causes the valve member to move upward and pull the valve element away from the valve seat.
