Wafer Butterfly Valve for Water Treatment Plant

Product Overview

Type: wafer butterfly valve, the hand-operated unit on a treatment header. Body: casting, wafer ends with no flange set of its own. Seal is single-eccentric, driven by a hand lever at the operating station. Ratings hold Pn10 and Pn16 across a band from -30°C to 400°C. Seat choice tracks the medium: soft for water duty, metal where the process climbs hot.

For water treatment plants the valve throttles aeration and filter backwash lines by hand. The compact wafer thickness saves pipe length where an air header runs between concrete piers. Cool water loops take the soft seat; hot process streams move to metal at the upper end of the temperature band. Industrial air circuits and household utility lines share the same wafer body, the hand lever holding any position the operator sets.
