The Butterfly Valve – Storz x NH Female Swivel Long Handle w/ Handwheel is designed to provide dependable flow control and positive shutoff for large-diameter fire service water supply systems. Featuring a bubble-tight sealing design and a handwheel-operated gear mechanism, this valve allows for controlled opening and closing to help reduce water hammer and provide smooth flow management during drafting, relay pumping, tanker operations, and large-volume water movement.

Constructed with a rugged cast iron body, aluminum bronze disc, stainless steel stem, and EPDM rubber liner, this valve is built for long service life in demanding fire service environments. The bi-directional design allows installation in either flow direction, while the body remains isolated from the water flow stream to minimize wear and corrosion. The handwheel operator features a fold-down knob for convenient operation and storage.
