The FVB-22-25.31 operating valve block is a separate pilot control system component. The block is intended to supply directly the connected cylinders (rams) in a powered roof support unit and to provide specified control functions. Embedded 3/2way operating (actuating) cartridges are activated from the FCB control valve block with a hydraulic control signal transmitted through the multihose. After opening the operating cartridge, the hydraulic medium flows to the specified space of the cylinder (ram). High pressure hoses are installed directly to the operating (actuating) valves. Control pairs are in the vertical plane.
