Abstract
A cartridge valve is arranged to control a flow of a fluid within a fluid supply network of a cutting machine such as mining or drilling apparatus. The valve includes a main body that defines an internal chamber to accommodate a reciprocating piston and plunger operative to open and close the valve by axial sliding movement. An intermediate region of the chamber provides a fluid tight partition between a working fluid network and a supply fluid network.
