Valves - APCO ASU Combination Air Valve

DeZURIK APCO ASU Combination Air Valve from DeZURIK Water Controls are single-body combination valves with an air release and air/vacuum mechanism to deal with media containing grit, solids and grease. They provide varied and predictable airflow over a wide range of air release conditions. A large diameter air/vacuum disc provides high-volume airflow 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 prevents air buildup and resultant flow restrictions under changing conditions and through the full flow range. It is available in 1- to 4-inch sizes with all stainless steel construction and meets the performance requirements of AWWA C512 standard. 320/259-2000; www.dezurik.com.
