A.R.I. USA

A.R.I. system solutions protect the pipeline from destructive forces such as surge, pressure transients and entrapped air. These are the leading causes of pipeline bursts, fractures and cracks which cause irreparable environmental damages such as water losses from leaks, pathogen and contaminant intrusion through pipe cracks and energy losses from inefficient flows. A.R.I. is committed to solving these problems by providing a system analyses that helps reduce surge related phenomena and select the most efficient A.R.I. air valves and size and locate them on the liquid transmission system.

Water Air Valves

A.R.I. air valves are an integral part of a water transmission system. These air valves will discharge air from a non–pressurized pipe enabling the efficient filling of the pipeline; continuously release air from a pressurized system, preventing the build-up of air pockets in the pipeline and admit large amounts of air into the system when vacuum conditions occur, protecting the pipeline from pressure transients and possible collapse.

Wastewater Air Valves

A.R.I. air valves for wastewater are specially designed to operate with liquids containing solid particles such as wastewater and effluents and liquids which can cause chemical build-up. The valve builds an air gap which separates the liquid from the sealing mechanism, ensuring optimum valve operation.
