MODEL D-040
The following is a step by step narrated description of the A.R.I. D-040 Combination Air Valve installation, operation and maintenance processes.
The D-040 series Combination Air Valve has the features of both an air release valve and an air & vacuum valve. The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure. Please consult A.R.I. for the pressure and temperature specifications table for this model and for other products designed for hazardous liquids systems.

Important: Before performing any work on the air valve make sure that all workers on site are familiar with the safety instructions and the relevant local and general safety instructions and work regulations.
2.1. Installation Recommendations
Single Air Valve on an Isolating Valve at 45° to Air Valve outlet |
Two Air Valves on a shared Isolating Valve. Air Valves outlets |
|
|
face outward and the Isolating Valve at 45° to Air Valve outlets |
|
|
|
|
|
|
|
Two Air Valves on an Air Trap with separate Isolating Valves. Air Valve outlets face outward and the Isolating Valves at 45° to Air Valve outlets
Underground Installations
Underground installations require a venting pipe from the manhole
Use an angular installation to bypass an obstacle directly above the pipeline.
