or distribution block controls in the valve actuator preferably determine the quantity of grease delivered to the stem or other device such as an anti rotation nut the u201c greaser u201d is a product which preferably combines a two filtration process with a powerful piston delivery element to give a rugged pump station to deliver grease to a valve stem preferably through a stem a lube fitting port the u201c greaser u201d may be mounted on a valve actuator or mounted up to 30 feet away in a convenient location the u201c greater u201d auto stem a lube has two methods of filling it may be filled by a standard grease cartridge or by a grease gun volume filler through a grease fitting on the chamber body in operation according to preset conditions such as when the actuator is operating or when the actuator is operating within a certain range of the valve and valve stem input signals are sent to the u201c greater u201d motor such that a start signal triggers the motor to begin pumping lubricant from the greater chamber through the communication line to surface areas of the valve stem preferably within a valve stem protector chamber a stop algorithm and or a timing signal signals the pump motor to stop the foregoing description of preferred embodiments of the invention is presented for purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the precise form or embodiment disclosed the description was.
