Rapidrop is a rubber faced, flanged swing type check valve that allows water flow in one direction only. A hinged clapper remains open with water flowing in one direction, and automatically closes, with the help of an incorporated spring, when flow stops preventing backflow. Removable cover allows easy access for inspection and maintenance. Rapidrop Fig.307 check valve is suitable for installation in both horizontal and vertical
position (with the flow upwards).
