4 inch butterfly valve Description
A 4 inch butterfly valve is a valve that is used to control the flow of fluid in a pipe. It is a quarter-turn valve, meaning that it can be opened or closed by rotating the disk a quarter of a turn The disk of a butterfly valve is a circular plate that is mounted on a shaft. The shaft is connected to an actuator, which is used to open or close the valve. When the actuator is turned, the disk rotates and either blocks or allows the flow of fluid.
When the actuator is turned, the disk rotates 90 degrees (a quarter turn) to either fully open or fully close the valve. In the open position, the disk is perpendicular to the flow of fluid, allowing the fluid to flow freely through the pipe. In the closed position, the disk is parallel to the flow of fluid, blocking the flow of fluid through the pipe.
