Forged Steel Leader valve - 150

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.
