Double Flanged Butterfly Valve

Valvesonly is a leading Double Flanged Butterfly Valve Manufacturer in USA. The valve, a type of flow regulation device within pipelines, employs a circular disc positioned on a rotating shaft. This valve showcases dual flanges on its ends, facilitating secure attachment between two pipes in a piping system. The disc, perpendicular to fluid flow when closed, rotates to an open position, permitting fluid passage. Manipulation of the valve occurs through a handle, gear, or actuator, which rotates the shaft, thus adjusting disc orientation. the valves can be operated manually or by actuators, with both methods functioning on the same underlying principle. They find utility in various scenarios, including on/off applications and regulating the flow of fluids.
