Abstract: A new and improved grease shunt valve and lubrication system for a printing press or the like is achieved by the adding of vent drains and/or seals to prevent the accumulation of a waxy-like residue from the grease that interfered with operation of a return spring for closing of the valve. An existing solenoid, operated, grease shunt valve may be retrofitted with an additional body portion having a grease drain vent therein and a seal that seals grease from flowing along a solenoid, actuating rod and into the solenoid core. Preferably, an end plug that seals one end of the return spring is drilled to provide the drain vent for grease flowing into the spring chamber. Vent holes may also be drilled into the solenoid housing to drain and vent grease flowing into the solenoid core.
