Reduced Bore, Combination Air Valve for Wastewater

A.R.I. D-025 is a reduced bore, Combination Air Valve installed on 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.

Features and Benefits

Conical body / funnel-shaped lower body

Maximum air gap, minimum body length
Residue matter falls back into the system pipeline

Continuous air gap

Separates the liquid from the sealing mechanism

Aerodynamic float assembly

High velocity air will not close the valve under rapid filling operation
Reduces accumulation of fat or grease buildup
Free movement will not unseal the sealing mechanism

Sealing assembly

Provides smooth, reliable opening/closing, and leak-free sealing over a wide range of pressures

Cushioned spring connection

Cushioned joint allows continuous air discharge under vibration conditions related to turbulence from pump start and shut-off, or from flow fluctuations.

Cover assembly

Allows complete drop-in replacement, reducing maintenance downtime
