ABSTRACT:
In the embodiment shown, the valve has a seat and a stop plate with valving elements therebetween. The seat has pluralities of openings formed therein, and the stop plate has a central void. The valving elements move, to open or close off communication between the openings and the void, in response to pressured fluid. Each element controls fluid flow through a pair of openings. The valve seat has angularly-formed lands with which the elements, correspondingly angularly formed, nest to close off fluid communication through the valve.
