ABSTRACT:
A control valve for fluids has two relatively rotatable plates, each having ports which cooperate to control fluid flow. The plates are biased towards one another, and one of the plates is provided with lands round its ports, these lands creating a space between the plates, to which space the fluid pressure at the valve inlet is admitted. The pressure between the plates opposes the inlet pressure acting on one of the plates, and the areas of the aforesaid one plate subjected to the inlet pressure are selected so as to produced a desired force between the plates.
