Pilot control unit
Product description:
Pilot control units (6 – 22 functions) enable the manual control of longwall operations.
Functional principle: The function is either performed directly by an HV4 directional valve impulse or via actuating a 3/2-way valve cartridge which will release the pressure to the actuated device. The returning hydraulic fluid is guided into the return line.
