Hydraulic Valves
- The Hydraulic Valve is a device that can change the opening degree of liquid (oil) flow path
- They are designed in a variety of styles to function in different applications. Valves are used to manipulate the flow of hydraulic fluid within a hydraulic circuit and are activated either mechanically or electronically.
Method of Control
Manually Operation, Mechanical Drive, Hydraulic Transmission, pneumatic Transmission ,Solenoid Drive, Electric-Hydraulic Drive ,Solenoid Proportion Drive
Directional Control Valves
- Directional control valves can control the start, stop and change in direction of flow of a pressure medium
- Hydraulic directional control valves should be selected based upon both the size of the circuits and the components, both upstream and downstream to the valve
- A directional control valve comprises at least two spool (switching) positions and two working ports.
- Flow ratings should be based upon the highest possible flow the valve will need to achieve.
