Ductile Iron Gate Valve, ANSI Flange, Rising Stem, Resilient Seat, for Water & General Services

Our ductile iron gate valve is engineered for superior performance in water supply, industrial pipelines, and general service applications. Constructed from high-grade nodular cast iron (QT450), this valve offers exceptional strength, impact resistance, and durability. It features a rising stem for clear visual positioning, a resilient seat with Nitrile rubber sealing for bubble-tight shut-off, and a handwheel operation for easy control. Compliant with ANSI standards and designed for pressures up to 150LB, this valve is ideal for systems requiring reliable isolation and minimal maintenance.

Product Feature
