Heavy Duty Sight Feed Valves

Heavy Duty Sight Feed Valves are similar to Small Sight Feed Valves but feature larger orifices.  The valves allow visual observation of the liquid stream, with the volume of flow controlled by an adjustable precision control needle valve. These units are principally used on gravity or pressure lubricating systems, including steam and gas engines, paper and sugar mill machinery, and many others.  Their use can be extended to any application requiring adjustable, visible flow control.
