The HQ41X Rolling Ball Check Valve features a rubber-lined rolling ball as the valve disc, which is actuated by medium pressure to roll on a track for opening and closing. It boasts strong sealing, noiseless closure, and no water hammer effect. Its core structure is a full water passage design, with high flow rate, low resistance, and a head loss reduction of 50% compared to the swing type.

Key Parameters
