The inclined angle can greatly reduce the water hammer and water hammer sound.
There are three parts that make up the rubber flap check valve. We can see it from the name of the rubber flap check valve: the valve body, the rubber flap and the valve cover. Therefore, the name of the rubber flap check valve is also derived from this. Come on, it's very easy for us to remember. This kind of rubber flap check valve is very easy to use.

Rubber flap check valve consists of valve body, valve cover, valve flap and spring, etc. It is mainly used at the outlet of pipelines in water supply and drainage systems, petroleum, chemical and other industrial sectors to prevent backflow of media. Due to the inclined design of the sealing ring of this product, the closing time is short, which can reduce the water hammer pressure. The valve disc is made of nitrile rubber and steel plate by high temperature pressing, which is resistant to erosion and has good sealing performance. The product structure is simple, maintenance, repair and transportation are very convenient.
