The HC44X rubber check valve is an automatic valve used for controlling the unidirectional flow of pipeline media. It features an inclined sealing ring design to shorten the closing time and reduce water hammer pressure. The core component, the valve disc, is made by high-temperature composite pressing of nitrile rubber and steel plate, offering abrasion resistance and sealing properties.

Application Range

Suitable for industrial pipelines in water supply and drainage systems, oil, chemicals, and power industries, it can prevent backflow of media.
