We provided our drawings with old design of air release valve to STABLE VALVES. Their engineer gave comment that our design is not reasonable, which affect the founction of air release. Flow Inlet and outlet have big resistance in old design. After we check the comment and advice from STABLE, we confirm if we change design according to STABLE VALVE, we can get better products with better function. Much thanks for STABLE VALVES team!
