Overview

The ZQV Stainless Steel Gate Valve delivers dependable on/off isolation in services where corrosion resistance and cleanliness are paramount. Cast from CF8 (304) or CF8M (316) stainless steel throughout, it resists attack from acids, chlorides and other aggressive media while providing a full-bore, low-pressure-drop flow path when open. The rising-stem, bolted-bonnet construction with integrally cast or hardfaced seats gives reliable shut-off, making the valve well suited to chemical, food, pharmaceutical and water treatment installations.
