Hydraulic Valve


a device in hydraulic machines and drives in which the dimensions of the operating channel vary as a result of the action of the hydraulic fluid passing through it. Hydraulic valves protect the hydraulic system and mechanisms of machines from overloads, provide a specified constant pressure in various branches of a hydraulic system, control the direction of fluid flow, regulate fluid pressure in the various branches of a hydraulic system, create a specified constant pressure drop in various parts of hydraulic systems, and provide a given sequence of actions of the working members in a machine for purposes of interlocking.
