A 6 Inch butterfly control valve is a versatile rotary control valve engineered to manage the flow of gases or liquids within a piping system. With its 6-inch diameter, roughly DN150, it efficiently starts, stops, throttles, or modulates flow by rotating a disc 90 degrees to control the flow passage size. This design allows for precise regulation in response to controller signals, making it an effective solution for applications requiring accurate flow control and adjustment.
