Quick supply unit for leg cylinders

Product description:
The quick supply unit for leg cylinders supplies the hydraulic fluid to the two leg cylinders directly from the pump pressure line. This allows roof supports with large-diameter leg cylinders to be quickly lifted and lowered.

Functional principle:
An impulse function actuates four 3/2-way valve cartridges at the same time. The cartridges release the fluid directly from the pump pressure line to the cylinders. The return flow is directly connected to the return line of the hydraulic longwall system.

P: pressure port (2 x)
R: return port (at least 1 x)
A: actuator port (4 x)
