D-46 | Combination Air Valve for High Flow
Description
A.R.I. D-46 Series, is a full-bore 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. The Air Valve provides high-capacity air release and intake.
Product Features
- Reliable operation - reduces water hammer impact,
saves energy and increases system efficiency. - Dynamic design - high capacity air discharge.
- One-piece lightweight body - lessens the chance of leaks and vandalism.
- Screened threaded outlet - insect-proof, for vent pipe connection.
- All internal operating parts - specially selected materials - non-corrosive and durable.
- Automatic air release orifice - high flow air release, lessens obstruction by debris.
- Minimum down-time for maintenance all operating parts in one replaceable cartridge
- Rolling seal - leak-free sealing over wide range of pressure differentials.
- Built-in drainage outlet - hygienic, drains surplus water above the sealing mechanism.
- ATEX certified air valves - certification is conditional on the customer connecting the designated part on the product to a dedicated ground connection point.
Materials and Corrosion Protection
- The body is made of high-strength composite materials.
- All operating parts are made of specially selected, corrosion- resistant materials.
