Control Valves used in the hydraulic system
Introduction to control valves In a general layout of the hydraulic system, after the pump, the next important components are present which are control valves. They are generally placed in between the pump and actuators. The pump generates a flow of oil which is fed to the actuators through a controlling element known as a valve. Basically, the valve is nothing but a device that controls the oil energy. Need for control valves 1. For blocking/stopping of flow of oil. 2. To control the direction of flow. 3. To control the pressure of oil. 4. To control the flow quantity. 5. Other special functions such as controlling the oil flow in one direction, diverting the flow, etc. Classification of control valves 1. According to construction a) Seat valves: The seat valve consists of a poppet that sits on a sp...
