In the hydraulic control element, which is the directional control valve
Control control or adjust the direction of the hydraulic system of the oil, pressure, flow driven actuators and its work mechanism to obtain the necessary direction, force (torque) and speed (RPM), etc. hydraulic
Directional control valves are: one-way valve and liquid-controlled one-way valve, electromagnetic directional valve, electro-hydraulic directional valve, manual reversing valve, multi-directional valve. Control the movement direction of the actuator Pressure control valve: relief valve, relief valve, sequence valve, balancing valve, unloading valve, pressure relay
Commonly used in the direction of the valve is generally divided into: check valve, reversing valve, multi-channel valve and cartridge valve (valve), etc., as the name suggests is a one-way control hydraulic one-way operation, the reversing valve control executive components (cylinders, motor) reversing, multi-way valve can control multiple actuators at the same time, oil use cartridge valve main implementation logic. The usual pressure valves are overflow valve, pressure reducing valve, sequence valve, pressure relay and so on. Because of the various types of hydraulic components, this is a different story
