Brief introduction
The three-position four-way directional valve is to control the fluid direction in the hydraulic system. Besides, it is a high-performance control component, widely used in hydraulic system, can accurately control the movement direction and speed of actuators in the hydraulic system. It is characterized by compact size, high stability and reliability, fast response speed, precise control, high sealing performance, excellent corrosion resistance and wear resistance.
Performance and features
The three-position four-way directional valve is mainly composed of valve body, spool, spring, seal and other components. When the spool moves inside the valve body, it changes the fluid passage to achieve direction change and flow regulation for fluid. By controlling the valve operation, the movement direction and speed of the actuators in the hydraulic system can be precisely controlled. Its advantages are as follows:
1. Compact structure, small size, easy to install and maintain;
2. Stable and reliable operation, fast response speed, and precise flow and direction control;
3. Excellent sealing performance, able to maintain good sealing effect under high pressure for a long time;
4. Strong corrosion resistance and wear resistance, suitable for harsh working environments.
