Water Butterfly Valve Elephant ggg50-316l-epdm-elephant-da-4m310-24v, body material - cast iron GGG50, disk material - stainless steel AISI 316L, seal - EPDM, pneumatic actuator operated Connection size:DN150 2 RDN-4 30:1 240 160A 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.
