The Oil-Rite small sight feed valves allow visual observation of the liquid stream, with the volume of flow controlled by an adjustable precision control needle valve. Their use can be extended to any application requiring adjustable, visible flow control.
These valves withstand up to 225°F and 125 PSI inlet to orifice pressure with vented sight chambers. They feature a steel plated valve body and needle assembly, glass sights, and a 1/16″ diameter port. The valves are 3″ or less in height.
All small sight feed valves have the outlet located on the bottom of the unit. They are available in four different patterns: Straight, Cross, Angle, and Inverted Angle. The patterns refer to the positioning of the inlet and needle valve adjustment on the valve. Each valve style has multiple selections of inlet and outlet threads to accommodate various applications.
The valves are available with vented or solid gasket construction. Vented sight chambers ensure proper flow and prevent airlock. Solid Gasket designs are available for sealed pressure applications.
