KM-type socket-equipped simple flap gate "KMGH model"

Fixed by covering the outside of the PVC pipe! Installed on the waterway side of the drainage pipe to prevent backflow during waterway flooding.

The "KMGH type" is a simple flap gate (backflow prevention valve) with a socket, 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 drainage 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 is fixed by being covered over the outside of PVC pipes. For diameters 50 and 65, to prevent clogging, the connection diameter is the same as the nominal diameter, but the valve diameter is enlarged to 75mm. 【Features of KMGH Type】 ■ The main body is made of PVC ■ Convenient for easily installing a flap gate ■ The main body is covered over the outside of the PVC pipe and fixed with adhesive, making it useful for new installations ■ Compatible sizes range from 50mm to 600mm in diameter ■ Applicable water depth: up to 2m ■ It does not provide 100% watertightness *For more details, please refer to the PDF document or feel free to contact us.
