TYPES OF VALVES?

By Admin on

1. Directional control valves (DCVs):


               They determine the path through which a fluid transverses a given circuit. 

Pressure control valves: 

                    They protect the system against over pressure, which may occur due to a sudden surge as valves open or close or due to an increase in fluid demand. 



2. Flow control valves: 


               Shock absorbers are hydraulic devices designed to smooth out pressure surges and to dampen hydraulic shock. In addition, the fluid flow rate must be controlled in various lines of a hydraulic circuit. For example, the control of actuator speeds can be accomplished through use of flow control valves. Non-compensated flow control valves are used where precise speed control is not required because the flow rate varies with pressure drop across a flow control valve. It is important to know the primary function and operation of various types of control components not only for good functioning of a system, but also for discovering innovative methods to improve the fluid power system for a given application.
