Hydraulic valve introduction
The function of the hydraulic control valve (referred to as hydraulic valve) in the hydraulic system is to control the flow direction, 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 motion, thrust (torque). And the speed of movement (speed) and so on. Any hydraulic system, no matter how simple it is, can not lack the hydraulic valve; the hydraulic mechanical equipment of the same process can be used in different combinations of hydraulic valves to form a variety of hydraulic system solutions with different oil passage structures. Therefore, the hydraulic valve is the most extensive, most widely used and most active part (component) in hydraulic technology; whether a newly designed or operating hydraulic system can operate normally and reliably according to the established requirements, to a large extent Depending on the performance of the various hydraulic valves used and the reasonable matching of the parameters.
