The forged steel globe valve adopts self tight sealing structure, and the sealing performance is good. The two ends of the branch pipe are welded. The valve clack and the valve seat sealing surface with Stellite (Stellite) cobalt based alloy welding and wear resistance, high temperature resistance, good anti abrasion performance. The stem is quenched and tempered and treated by surface nitriding. Valve cover stuffing box depth reasonable filler plus corrosion inhibitor sealed reliable.

1, Product design and manufacture according to ANSIB16.34, E101 standards, can be equipped with imported equipment.
2, The valve cavity using self tight sealing structure, the higher the pressure inside the cavity, the better the sealing performance.
3, The valve and the valve seat sealing surface with Stellite (Stellite) cobalt based alloy welding and.
4, The valve cover stuffing box depth reasonable, filler plus corrosion inhibitor, sealed reliable, smooth switching.
5, The valve has an upper sealing structure, to ensure that the valve opening without leakage of the valve stem.
Forged steel globe valve is a commonly used cut-off valve, mainly used to connect or cut off the pipeline medium, generally not used to regulate flow. Valve for a wide range of pressure and temperature, the valve is applicable to small caliber pipeline, the sealing surface is not easy to wear, abrasion, good sealing performance, opening and closing the valve stroke is small, open and close in a relatively short time, little height of valve. The valve has an inverted sealing structure to ensure that the valve does not leak out of the valve stem when it opens. Widely used in petroleum, chemical, natural gas, metallurgy, chemical fiber, paper making, urban construction and other fields.
