Abstract: A valve assembly includes a valve seat having a valve opening therein. A valve plate is configured to sealingly engage the valve seat in a closed position for closing the valve opening to thereby close a fluid path through the valve assembly, the valve plate being biased toward the closed position by a first spring. An actuator plate can include an inlet opening therein, the actuator plate being biased in a direction away from the valve plate by a second spring. A member includes a first end fixed to the actuator plate, an interior passage in communication with the inlet opening in the actuator plate, and a second end engageable with the valve plate when a portion of the member passes through the valve opening of the valve seat, wherein the valve plate is configured to open in response to direct fluid pressure when fluid is guided to the valve plate by the member or when fluid pressure on the actuator plate is transmitted to the valve plate via the member.
