Just fit it and tighten it firmly. Yamato's unmanned, non-powered fume flap.
To prevent backflow from rivers into drainage ditches during water discharge, various gates are installed at the drainage outlets. Among these, it is common for small drainage outlets to have flap gates that automatically open and close based on the difference in water levels inside and outside. In this case, although the gate itself is quite small, the construction involves significant additional work, such as pouring the necessary concrete for installation, sometimes creating temporary closures for this purpose, and using drainage pumps. Our company has focused on this aspect and developed the Daiwa-style automatic drainage device, the Hume Wrap, which can be installed simply by inserting it into the end of a Hume pipe and tightening bolts, significantly reducing construction costs and achieving thorough rationalization.

basic information
**Features** ● The water-tight door stop does not require any additional equipment. The water-tightness is achieved by a specially shaped rubber that adheres to the thick surface of the fume pipe, completely preventing backflow. This is the key point for reducing construction costs. ● Attention has been paid to corrosion resistance. There are two types of materials: SS (steel) and SUS (stainless steel). The SS version is treated with zinc plating followed by paint coating to enhance corrosion resistance. If additional anti-corrosion and durability are required, please choose the SUS version. ● Products are delivered promptly.
