Quarter-turn plastic butterfly valves for extra-large diameter applications. Engineered for maximum flow capacity with equal percentage flow characteristics and moderate flow control for versatile service.
Maximum capacity engineering
Available in 18", 20", 22", and 24" sizes for maximum flow capacity applications.
403 stainless steel stem with full disc engagement completely isolated from process media.
Precision engineered seating ensures bubble-tight shut-off for zero leakage performance.
Only abrasion-resistant solid plastic disc and elastomeric liner contact the media.
Industry-leading Rotork® gear operator for reliable and smooth operation.
Equal percentage flow characteristics for both ON/OFF and modulating service.
Good tolerance to suspended solids for versatile industrial applications.
Available in both wafer and lug style configurations for installation flexibility.
Extra-large diameter range (18" - 24") provides maximum flow capacity for high-volume applications.
Standard PP body, disc and EPDM seat provide excellent chemical resistance for aggressive media.
Robust polypropylene construction ensures durability in demanding industrial environments.
Multiple stem options including 403 SS, 316 SS, Titanium, and Hastelloy C® for specific applications.
Designed for pneumatic and electric actuation with Rotork® gear operator standard.
Specifically engineered for landfill applications and other demanding industrial uses.
