1.Prevent the medium from flowing back.
2.Short structure length, suitable for working conditions with small installation space.
3.The valve plate closes quickly and the water hammer pressure is small.
4.Both horizontal pipes and vertical pipes can be used, easy to install.
5.Unobstructed flow channel and low fluid resistance.
6.The built-in wafer butterfly check valve has no external leakage points.
7.Adopt epoxy spraying(stronger adhesion and good weather resistance).
8.Pressure Testing Report,Certificate of Material and FORM E Certificate Of Origin can be provided.
