Abstract
A plate valve is presented in which flow losses are reduced and effective flow area is maximized by establishing a ratio of effective seat area (Fs) to area between the plates (Fb) such that Fs/Fb is between 0.4 and 0.8. The spacing between plates is higher compared to the width of the plates than in the prior art, and the width of the plates may decrease for plates of increasing diameter.
