Multiple Sight Feed Valves allow visual observation of the liquid stream, with the volume of flow controlled by an adjustable precision control needle valve. The simple-to-use modular design allows the compact unit to be changed by stacking valves together. These units are especially suitable for lubricating inaccessible spaces and widely separated points. They are principally used on gravity or pressure lubricating systems in a variety of industries such as chemical mining, paper, agricultural, marine, woodworking, and textile.The sight feed valves can also be used to lubricate equipment like pumps, compressors, machine tools, bearings, seals, punch presses and rollers. Their use can be extended to any application requiring adjustable, visible flow control.
Add-On Valves are for use with existing Multiple Sight Feed Valve manifolds. Each Add-On Valve is equipped with a patented Threadapter connection that attaches easily to an existing Multiple Sight Feed Valve group.
