D-025 | Combination Air Valve for Non Clean Water
Description
A.R.I. D-025 Series is a reduced bore, Combination Air Valve installed on a wastewater transmission systems. The Air Valve is designed to improve hydraulic operation by protecting the pipeline, increasing pipeline efficiency, and reducing energy requirements. The unique body shape of the valve, enables a continuous air gap that separates the wastewater from the sealing mechanism and helps to avoid deposits or blockage. Applicable for: Desalination & Sea Water, Mines, Marine - Ballast Water, Oil & Gas, Food Industry, Power Plant Cooling, CBM, Hydro / Thermal Power.
Main Features
- Size Range 2” - 4”
- Sealing pressure range 0.05 - 10 bar (PN10)
- Testing pressure: 1.5 times maximum working pressure
- Temperature Maximum working temperature: 60° C
- Maximum intermittent temperature: 90° C
Valve Selection
- Conical body shape & unique design - maximum air gap / minimum body length.
- Continuous air gap - separates the liquid from the sealing mechanism.
- Float assembly and sealing mechanism linkage - free movement, turbulence will not unseal the sealing mechanism.
- Funnel-shaped lower body - residue matter falls back into the system pipeline.
- Rolling seal mechanism - leak-free sealing over wide range of pressure differentials.
All parts are suitable for corrosive liquid and environment - non-corrosive and durable parts. - Screened threaded outlet - compatible for vent pipe connection, prevents insect intrusion.
- Dynamic design - high capacity air discharge, no premature closure.
- Tap - releases pressure and drains valve prior to maintenance.
Installation:
- Wastewater & water treatment plants
- Wastewater and effluent water transmission lines
- Industrial water transmission lines and applications
