Diagram: Dimensional drawing showing wafer butterfly valve in front elevation and cross-section. Left side shows front face with bolt circle (ØD1, n-Ød1) and overall diameter. Right side shows cross-section with labelled dimensions: C (face-to-face length), d0 (bore diameter), g (top flange PCD), h (top flange height), p (bottom shaft diameter). Bottom views show actuator ISO flange with z-Ød bolt pattern, ØE and ØK diameters, and stem dimension b. Seven component parts are numbered (1–7) on the cross-section.

Description

A wafer-type butterfly valve engineered for flue gas desulfurisation (FGD) systems, wastewater treatment, and corrosive media handling. Constructed with a resilient seat design to achieve bubble-tight shut-off and flow control in abrasive slurry, acidic, and elevated-temperature service conditions. Available in a range of body, disc, and stem materials to suit varying corrosion and abrasion requirements.
