DT-040 | Micro Combination Air Valve
Description
A.R.I. DT-040 Series, is a reduced bore Micro Combination Air Valve. Installed on liquid transmission systems, the Air Valve is designed to improve hydraulic operation by protecting the pipeline, increasing pipeline efficiency and reducing energy requirements.
Product Features
- Combines the features of both an air & vacuum valve and an air release valve.
- Triple function:
- Air & vacuum component discharges large volumes of air during filling of the system.
- Air & vacuum component admits large volumes of air during drainage and at water column separation.
- The air release component releases entrapped air in pressurized systems.
- Dynamic design allows for high velocity air discharge while preventing premature closure.
- Simple and reliable structure , small dimensions, lightweight.
- Available in sizes: 2" threaded male or female BSPT/NPT connections, BSP,NPT. Sizes 3" – 6" are manufactured with flanged ends to meet various requested standards.
