Views: 264 Update Date: May 04 , 2018

The function of hydraulic control valve in the hydraulic system is to control the flow, pressure, and flow of the oil in the hydraulic system, so that the actuator and its driven working mechanism can obtain the required direction of movement, torque and speed. Any hydraulic system, no matter how simple, can not be lack of hydraulic valve; the same technological purpose of the hydraulic machinery equipment, through the use of different combinations of hydraulic valves, can be composed of a variety of hydraulic system structure of the hydraulic system. 


Therefore, the hydraulic valve is the most variety and the most widely used and the most active part in the hydraulic technology; a newly designed or running hydraulic system can run normally and reliably according to the established requirements, depending to a large extent on The advantages and disadvantages of various hydraulic valves used and the matching of parameters are reasonable.
