All ports, safety valves and check valves are centrally arranged on the top of the valve body, which is compact and easy to arrange
The safety valve adopts a combination of pressure control cone valve and unloading slide valve, and has good opening and closing characteristics, which can reduce heat generation during overflow of large flow rate
The circuit has a pressure output port that can be used as an oil source for subsequent hydraulic components
Dual mode control: pneumatic control and hydraulic control respectively; hydraulic pilot control adopts double spring structure to realize four-position floating
