APCO Single Body Combination Air Valves from DeZURIK can be used for clean or dirty fluids. The venting design provides predictable air flow over with low pressure sealing down to 2 psi. The compact design of the ASU combination air valve allows for installation in piping systems with limited space and in vaults with low ceiling heights. The valves are suitable for corrosive conditions with a 316 stainless steel body and have a large-diameter air and vacuum disc.
