PTFE Lined Butterfly Valve for Chemical Industry Phosphoric Acid / Hydrofluoric Acid

Pneumatic piston fluorine lined on-off butterfly valve

General

ZSHWJ/ZDRWJ/ZSHWF/ZDRWF series lined butterfly valve are designed for desulfurization denitration device and slurry piping system, especially for corrosive application, such as sulfuric acid, phosphoric acid, hydrofluoric acid, chlorine, alkali, aqua regia and other strong corrosive media, requiring reliable shut-off performance, good corrosion resistance and long service life.

Characteristics

Fluorine lined butterfly valve lined with PTFE, the elastomer back-up pads behind the liner ensure a tight fit around the disc, for a bubble tight shut-off. With advantages of easy operation, good sealing performance, long service life and quick shut off or control feature. Split body design is not only easy to replace shaft but also easy to adjust sealing performance. The connection is wafer.
