Actuated Butterfly Valves 101: All You Need To Know About Their Application In Piping Systems
Control of the opening and closing of the valves, for isolation or throttling service, relies upon a centrally placed disc attached to a rod or shaft passing through it and connected externally to an actuator. Turning the actuator aligns the disc perpendicularly or parallel to the direction of the fluid flow. Valve discs are of equal radial dimensions as the bore, and are continuously present in the flow - inducing a limited pressure drop in the system.Butterfly valves are classified based on the disc closure type and the design of the ends of the valve body.
