Universal (Bulls-Eye) Sight Feed Valves allow visual observation of the liquid stream from a distance, with the volume of flow controlled by an adjustable needle valve. The bulls-eye sight feed valve has excellent flow characteristics with low pressure drop. These units are principally used on gravity or pressure lubricating systems of larger machinery where considerable capacities of oil must be dispensed. The sturdy construction makes them especially suitable for paper mill machinery, steel mills, rolling mills, sugar mills, steam and gas engines, gear units, etc. Their use can be extended to any application requiring adjustable, visible flow control.
Large glass sight windows on both sides of the valve are gasketed to prevent leakage and permit excellent observation of the liquid stream. Threaded retaining rings on both sides secure the glass. The sights can easily be removed for cleaning or replacement without disconnecting the valve.
The vent in the sight chamber ensures proper flow and prevents airlock. When the vent is replaced with a solid pipe plug (part no. A4167-1), maximum sight chamber pressure is 55 PSI.
This tamperproof valve withstands up to 225° F and 125 PSI inlet to orifice pressure. The valve features steel plated needle assembly, gold anodized aluminum valve body, 1 1/2” diameter sight glass, Buna-N seals, and 1/4" diameter port. Total Height of the valve is 6 21/32”.
(3) 3/8” Female NPT inlets are provided as well as a 3/8” Male NPT outlet.
