Abstract
The invention relates to a priority valve for a hydraulic installation having a main circuit and an auxiliary circuit. The priority valve has a slide member which primarily has a controlled throttle for dividing the supply fluid between the main and auxiliary circuits in accordance with the priority demands of the main circuit. The priority valve has a flow path leading to the auxiliary circuit which has throttle elements in series which provide pressure drops in steps to minimize cavitation when there is a rapid flow of fluid in the auxiliary circuit.
