Convenient for later installation! PVC flap gate that can be installed by inserting it into existing pipes.
The "KMGC type" is a plug-in type simple flap gate (backflow prevention valve) installed on the waterway side of drainage pipes such as rainwater drainage pipes to prevent backflow during rising water levels. Under normal conditions, it allows rainwater to flow into the waterway, and during flooding, the flap gate closes to prevent backflow. Recently, there has been an increase in its use for drainage pipes installed on the parapet walls of rivers. It is also used to prevent odors and the entry of pests from drainage pipes. It can be easily installed by inserting it into existing pipes, making it convenient for later installation. The shape and installation method vary depending on the nominal diameter, so please specify the pipe diameter and type when ordering. <With flange type> for diameters from 75 mm to 150 mm If the surface of the pipe you wish to install this diameter (type) on has a slope, please request a sloped processing product. <Without flange type> for diameters from 200 mm to 400 mm Products of this diameter (type) can be used with or without a slope. *For more details, please refer to the PDF document or feel free to contact us.
