Small Sight Feed 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 for bearing lubrication on machinery. Their use can be extended to any application requiring adjustable, visible flow control.
There are two inlets on either side of the valve body, with the outlet located on the bottom. The needle valve adjustment is on the top. The solid gasket design is used with a sealed pressure system. Vented designs are also available.
This handwheel valve (tamperproof is also available) withstands up to 225° F and 125 PSI inlet to orifice pressure. The valve features a steel plated valve body and needle assembly, glass sights, Buna-N seals, and a 1/16" diameter port. Total Height of the valve is 2 15/16”.
The valve has a 1/4” male NPT inlet and a 1/4” male NPT outlet.
