摘要： A system for distributing high viscosity grease to at least one plug valve includes a replaceable cartridge with a body having a chamber and a piston disposed within the chamber. The piston defines a first space within the chamber for receiving solid grease and a second opposing space within the chamber for receiving fluid for driving the piston to compress the solid grease received within the first space. A manifold detachably couples to the replaceable cartridge and has a manifold chamber for receiving grease flowing under compression from an outlet of the cartridge and a plurality of valves in fluid communication with the manifold chamber for selectively distributing grease to corresponding grease ports of the at least one plug valve.
