ABSTRACT:
The valve employs a buffered valve seat; a buffer plate is interposed between the seat and the valving element. Consequently, the valving element can manifest an increased lift, whereby the valve will offer an improved performance, as the buffer plate dampens the impact of the valving element during valve closure. Springs accelerate the return of the valving element toward the seat and, as the buffer plate has no spring-assisted seating, it intercepts the valving element in its closure. A guide ring shoulder restricts the lift of the buffer plate.
