HQ44X micro resistance ball check valve/HQ45X micro resistance ball check valve uses rubber coated ball as the valve disc, which can roll on the slide inside the valve body under the action of the medium T to open or close the valve. High flow rate, low flow resistance loss, good sealing performance, noise reduction, and closure can reduce water hammer waves. It can be installed horizontally or vertically. Can be used for preventing medium backflow at the outlet of water pumps in cold water, hot water, industrial and domestic sewage pipelines.
