Water Butterfly Valve Elephant WBV3432N-2W-Fb-H PN16, body material - carbon steel WCB, disk material - stainless steel 316L, seal - NBR, handwheel operated Lift Check Valve 9 40 200±2 150 110A water butterfly valve is a type of valve used to control the flow of water or other fluids through a pipeline. It gets its name from the butterfly shaped disc inside the valve that rotates to open or close the flow. When the valve is fully open, the disc is positioned parallel to the flow direction, allowing unobstructed passage of water. When the valve is closed, the disc is turned perpendicular to the flow, effectively blocking the flow of water.
