Product Overview
The wafer butterfly valve is a compact isolation and flow-control valve for general industrial piping — water, utilities, chemical lines and process duties where a lightweight quarter-turn solution is preferred.
The disc rotates a quarter turn from fully closed to fully open, with the seat providing sealing against the disc in both directions. Lever operation suits smaller sizes, gear box operation larger sizes and higher torques.
For control duties, the valve can be supplied as a complete automated package with pneumatic or electric actuation — assembled, accessorised and checked by GPRO before delivery.
