The HC44X rubber disc check valve consists of a valve body, a valve cover, a valve disc, and a spring. It is mainly used at the outlet of pipelines in industrial sectors such as water supply and drainage systems, petroleum, and chemical industries to prevent medium backflow. Due to the inclined design of the sealing ring of this product, the closing time is short, which can reduce water hammer pressure. The valve disc is made of nitrile rubber and steel plate pressed at high temperature, which is resistant to erosion and has good sealing performance. The product has a simple structure and is easy to maintain, repair, and transport.
