A.R.I. Flow Control Accessories products

The D-46 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.

The D-96 integrates the D-46 2” Combination Air Valve with the added feature of a sub-surface compact housing. A unique Check Valve allows for the disconnection and removal of the air valve from the housing without the need to shut down the flow of the pipeline, even when under line pressure

The following is a step-by-step narrated description of the A.R.I. D-040 L ARISENSE industrial combination air valve installation, operation and maintenance processes.

A.R.I. D-021 is a reduced-bore ultra-compact combination air valve installed on a raw water transmission system to increase pipeline efficiency and reduce energy requirements by improving the hydraulic operation of the system. A continuous air gap at the top of the air valve separates the reclaimed water from the sealing mechanism.

The D-43 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.
