APCO ASU combination air valve

12 December, 2014

DeZurik/APCO/Hilton has introduced the APCO ASU combination air valve, a new concept in air valve technology. This single body combination valve features a patented air release and air/vacuum mechanism that is specifically designed to deal with media containing grit, solids and grease.

The design provides varied and predictable air flow over a wide range of air release 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.

Lightweight, compact design

The ASU Valve is a universal design that allows application on a wide range of flow conditions with effective sealing and operation from 2 psi to 150 psi as standard. The lightweight, compact design of the valve allows installation in piping systems with limited space and in vaults with low ceiling heights. Available in sizes 1-4” with all stainless steel construction, the ASU combination air valve meets the performance requirements of AWWA C512 standard.

Backed by extensive field experience on tough applications, the ASU valve has demonstrated improved performance, reduced maintenance and lower cost for overall reliability on sewage and dirty service applications.
