Wholesale Various Style SS Manual Butterfly Valve

The manually clamp butterfly valve, commonly known as the manual wafer butterfly valve, is a type of valve that controls fluid flow through manual operation. It mainly consists of a valve body, valve plate (butterfly plate), clamping device, handwheel bracket, and sealing components. Its structure is compact, making it easy to install and maintain.It is particularly suitable for situations requiring frequent opening and closing, as well as regulation of fluid flow, such as flow control and media cutoff in piping systems. Working Principle: The manual wafer butterfly valve operates by rotating a handwheel or handle on the valve body, which in turn drives the valve stem to rotate. This rotation, in turn, drives the valve plate (butterfly plate) to rotate between 0 and 90 degrees, enabling the valve to be opened and closed. When the valve plate is fully open, it forms a 90-degree angle with the valve seat, allowing a large amount of fluid to pass through. When the valve plate is closed,…
