Electro-hydraulic control units for low seam operations

Product description:
With these electro-hydraulic control units (2 – 12 functions) for low seam operations, longwall operations can be controlled fully automatically. They are actuated by an electronic control device.

Functional principle:
An electric impulse is sent to a 3/2-way valve cartridge which releases the pressure to the actuated device. The returning hydraulic fluid is guided into the return line.
