The automatic air release valve integrates the advantages of traditional double - port air release valves and single - port quick air release valves. It features an innovative design with advanced technology that enables the air - tight sealing ball to always stay on the same sealing arc surface, resulting in excellent sealing and air release performance. In contrast, during the air release process of ordinary air release valves, the sealing ball rotates rapidly. Similar to a ping - pong ball surging upwards in a glass bottle, it constantly changes the sealing arc surface, which leads to leakage.

The unique dual - port design for rapid air release, micro - air release, and automatic air intake enables the air release valve to dynamically and automatically switch its operation mode according to the air volume. The stainless - steel sealing ball and stainless - steel basket can withstand low temperatures down to -20°C without bursting.
