**Overview**
The HQ41X, HQ44X, and HQ45X are low-resistance, wear-free ball check valves that utilize a rubber ball as the sealing element. These valves operate by allowing the ball to roll or slide within the valve body under the influence of the medium flow, enabling smooth opening and closing. They offer quiet operation with no water hammer effect and excellent sealing performance. The design features a full-bore passage, which reduces flow resistance and results in a 50% lower head loss compared to traditional rotary valves. These valves are suitable for both horizontal and vertical installations in cold and hot water systems, industrial pipelines, and domestic water networks. They are especially recommended for use with submersible sewage pumps, where the operating temperature does not exceed 80°C.
