Project Description

Butterfly valve used for isolating or regulating flow. The closing mechanism takes the form of a disk allows for quick shut off. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. In butterfly valve a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid.

Carefully design dies in Addcon make butterfly valves, for integrally moulded elastomer which performs as soft seat, gives long life and hassle free operating cycles and valuev for the money. Disc and an integrally moulded (bonded) soft seat offer 100% bi-directional sealing against vacuum to rated pressures of PN10. The wafer style body has universal design to fit between pipe flanges of almost all popular flange standards.

Addcon Butterfly Valves are Wafer Type design. Concentric design Butterfly Valves are reliable, maintenance free shutoff with permanently gas-tight seal with an integrally moulded or replaceable body liner. The wafer type design of Addcon valve body has universal design to fit between pipe flanges of almost all popular flange standards. However it is designed to meet the demanding requirements of market.
