Adamant - Model AV-1EC -Electric Operation Sanitary Actuated Butterfly Valve
The electric actuated butterfly valve uses a circular disc contained within a ring style body that sandwich mounts between pipe flanges, which rotates by a quarter turn by a central shaft with a seal typically created by the outer edge of the disc compressing a resilient rubber seal located within the ring, as the valve closes. Body styles are typically either wafer type or fully lugged and tapped to suit either metric or ANSI flanges, although double flanged or groove ended versions are available. Electrically actuated butterfly valves allow the position of the butterfly valve to be automatically (or motorized) controlled remotely whereas manually operated butterfly valves require human intervention at the physical location of the valve. Compared with the more traditional flanged gate valves, an actuated butterfly valve is lighter in weight making it easier to install, and offers more favorable pricing.
