Product overview

HQ44/45X micro resistance spherical check valve uses rubber coated ball as valve disc. Under the action of medium, it can roll on the slide in the valve body, so as to open and close the valve. Large flow, small flow resistance loss, good sealing performance, silencing and closing, which can reduce water hammer wave. Install evenly horizontally or vertically. It can be used at the pump outlet of cold water, hot water, industrial and domestic sewage pipe networks to prevent medium backflow.
