APCO High Performance Combination Air Valve (ASU)
APCO Single Body Combination Air Valves (ASU) are a high performance valve that can be used for clean or dirty services. The unique and patented venting design provides varied and predictable air flow over a wide range of air release and air/vacuum conditions. A large diameter Air/Vacuum Disc provides high volume air flow for rapid venting during pipeline filling and allows high volumes of air to enter the pipeline during draining. During normal pipeline flow conditions, the dual-range air release design prevents air build up and resultant flow restrictions under changing conditions and through the full flow range.
