Pilot-direct control unit

Product description:
This compact pilot control unit combines both the pilot control and the main control functions in one unit and is used for the manual control of longwall operations. The multi-hose enables shield-to-shield control.

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.

P: pressure port
R: return port
