Pilot control units for low seam operations
Product description:
These pilot control units (6 – 12 functions) are designed for the manual control of longwall operations in low seams.
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.
