direct acting

The Direct Acting Spool Type Cartridge Relief Valve is a pressure control valve that combines the characteristics of a direct-acting relief valve with an LS (Load Sensing) port. The direct-acting relief valve uses the principle of balancing the liquid pressure on the valve core with the spring force to control the opening and closing of the valve, thereby adjusting the system pressure; the LS port is used to introduce a load pressure signal, so that the relief valve can more accurately control the system pressure according to the load changes.
