Hydraulic Valve
The Hydraulic Valve actually, is a device that can change the opening degree of liquid(oil) flow path
They are manufactured 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.
By Control Way
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.

After purchasing such a high-quality hydraulic directional valve, how should we maintain it in order to better extend its service life? You need to pay attention to the following points:
1. Before buying a hydraulic reversing valve, you must fully consider whether the hydraulic oil pressure in the hydraulic system you need to use meets the reversing requirements. You must purchase a qualified hydraulic reversing valve to better play a positive role.
2. When installing the hydraulic directional valve, you need to pay attention to the position of the oil inlet and return port of the valve body. The positions of the oil inlet and oil return port of different types of hydraulic directional valve may be slightly different. If you accidentally install the oil inlet and return ports of the valve body upside-down, an operation accident will occur, which will cause irreparable problems.
3. Pay attention to the sealing condition of the connection, and not allow air circulation to pollute the fluid. An absolutely sealed environment should be created to fully ensure the stable operation of the hydraulic system.
4. Check the hydraulic reversing valve regularly and pay close attention to whether the hydraulic reversing valve has internal or external leakage. Once the valve body is damaged, it must be replaced in time to avoid serious consequences.
