STAINLESS STEEL DN300 Manual Indicator Anti Mixing Butterfly Valve

The stainless steel DN300 manual indicator anti-mixing butterfly valve operates by rotating a central disc within the valve body using a manual handwheel or lever. When the disc turns parallel to the flow, the valve opens, allowing fluid to pass with minimal resistance. In the closed position, the disc presses tightly against the valve seat, creating a reliable seal to prevent leakage or backflow. The anti-mixing design ensures unidirectional flow and prevents cross-contamination between different media. A manual indicator shows the valve’s open or closed position for easy visual monitoring. The stainless steel construction provides corrosion resistance and durability for industrial and sanitary pipeline applications
