The HQ44X Non-Wearing Ball Check Valve features a rubber-coated ball as the valve disc, which is actuated by medium pressure to roll within the valve body for opening and closing. It boasts large flow capacity, minimal flow resistance loss, and superior sealing performance. The sealing is achieved through the tight fit of the rubber layer with the valve seat, effectively preventing backflow of the medium and reducing the impact of water hammer waves on the pipeline system.
