And the corrosion-resistant resin, covering the whole contact surface, makes the valve highly resistant against chemical and sea water. ■ Light Weight PDCPD having 1/4 or less the specific gravity of iron, the PDCPD BUTTERFLY VALVE is significantly lighter than a metallic butterfly valve. ■ Tight Seal A seat made of a synthetic rubber, makes the valve highly water-tight. ■ Excellent Flow Characteristics Being concentric and streamlined, the disc gives small resistance to a flow, thus allowing it to be laminar. The seat is kept clean, since it is integrated with the entire internal wall of the body. ■ Easy to Install The seat is flanged, so that it needs no gasket. The PDCPD BUTTERFLY VALVE is so light that it is easy install. ■ Economics Because of its high corrosion resistance, the PDCPD BUTTERFLY VALVE remains easy to operate after prolonged periods of use and needs little maintenance. Its light weight reduces piping costs.
