Forged Steel Gate valves have a rising stem and Globe valves have a rising handwheel. The position of the stem or handwheel helps in identifying whether the valve is in Closed or Open position. Flanged valves are supplied with welded on flanges made of the same material as the body material. Bolted body-bonnet/cover joint with spirally wound stainless steel gasket for maximum protection against leaks. Die formed packing rings of flexible graphite with braided end rings to arrest gland leakage. Gate valves have - "T" head stem connection to ensure disc-seat alignment - Tapered shoulder on the stem for back seating - Outside Screw and Yoke (OS & Y) which prevents corrosion of the stem by the line fluid.
