Heavy Duty 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, 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.
The inlet and outlet are in an angle configuration, with the inlet on the side of the body and the outlet on the bottom. The needle valve adjustment is located on the top of the body. The solid gasket design is used with a sealed pressure system (vented designs are also available).
This tamperproof valve (handwheel 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 1/4" diameter port. The total height of the valve is 5 15/32 and width is 1 7/8".
