D-016 | Combination Air Valve for Industry
Description
The D-016 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.
The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.
Main Features
- Working pressure range: 0.2 - 64 bar
- Testing Pressure: 1.5 times the working pressure of the air valve
- Maximum working temperature: 60° C.
- Maximum intermittent temperature: 90° C.
Note: For applications requiring a working temperature above the maximum stated or below 50 C., please consult first with the A.R.I. Applications Engineering Dept.
- Reliable operation reduces water hammer incident.
- Dynamic design allows for high capacity air discharge while preventing premature closure
- Lightweight, small dimensions, simple and reliable structure
- Special orifice seat design: assures long-term maintenance-free operation
- The discharge outlet enables the connection of a vent/drain pipe
Air Release Component
- Body made of high strength materials
- All operating parts are made of specifically selected corrosion-resistant materials
- Large orifice:
- Dramatically reduces the possibility of obstruction by debris
- Releases high air flow rates
- One size orifice for a wide pressure range (up to 64 bar), achieved by utilizing the rolling real mechanism
Materials and Corrosion Protection
The A.R.I. line of industrial products is manufactured from the most advanced and highly corrosion-resistant materials and coatings. The specific materials and coatings for these products are specially selected to meet the requirements of each specific industrial process in order to ensure maximum protection.
Valve Selection
- The D-016 combination air valves are available in sizes 2”, 3” 4”, 6” & 8”
- These valves are manufactured with flanged ends to meet any requested standard
- The automatic air release component and the air & vacuum component are available as separate units
Note
For best suitability, it is recommended to send the fluid chemical properties along with the valve request.
Upon ordering, please specify: model, size, working pressure, thread and flange standard and type of liquid.
