|Innovative Valves for Industrial Applications|
A.R.I. Flow Control Accessories is among the world leaders in the development, manufacture and distribution of liquid transmission accessories. A.R.I. engineers have developed a wide range of sophisticated valves made from various me
Most of the A.R.I. products are protected by registered patents. A.R.I. operations, development and marketing systems comply with the requirements of the international ISO 9001 and ISO 14000 standards and are certified as such.
The A.R.I. Commitment
A.R.I. is committed to respond to the needs of a changing market. To do so, we strive for a high standard of quality, innovation and advanced technological development as our principal objective.
At A.R.I., we focus on providing products with longevity and minimal maintenance. We offer a comprehensive warranty, excellent service, consulting and training for each customer – at the plant, in the field or at any installation site, as necessary.
The A.R.I. line of automatic air release valves is based on the rolling seal technology. The A.R.I. patented sealing mechanism replaces traditional configurations that incorp
The self-cleaning feature of the rolling seal mechanism greatly reduces the possibility of clogging, leaking and the adhesion of suspended particles to the rolling seal surface.
The valve body and interior components are made of corrosion-resistant materials. This ensures years of corrosion-free and maintenance-free operation, even under extreme environmen
The A.R.I. line of industrial products also includes a wide variety of air & vacuum and combination air valves. They are made of the same quality materials as the automatic air release valves and provide the same level of quality and assurances.
These valves are offered in dimensions of 1/2” to 1” (automatic air release valves) and 1" to 10"(air & vacuum and combination air valves). They provide solutions for various applications in all industrial fields. These products are lightweight, have a compact profile and are offered at competitive prices.
Air in Industrial Liquid Transmission System
The quantity of air must be controlled in industrial liquid transmission systems. The presence of air/gas bubbles and pockets can be beneficial or detrimental to the transmission system under different conditions. The absence of air, such as exist under vacuum conditions, prevents suitable protection for the transmission systems.

Using A.R.I Air Valves to Control Air and Prevent Damage
There are three principal types of air valves used in industrial applications:
Air & Vacuum Valves automatically discharge air at high flow rates during filling of the system and intake air at high flow rates during draining, at water column separation, and in cases of down-surge in the system.
Air & vacuum valves are known also as: large orifice air valves, vacuum breakers, low-pressure air valves and air vacuum valves.
Automatic Air Release Valves release air entrapped in the system while under pressure. The air release flow rates of the automatic air release valves are lower than those of the air & vacuum valves. They are also known as: air release valves and small orifice air valves.
Combination Air Valves include both air & vacuum and automatic air release components in one unit. They perform both functions:
Combination air valves are also known as double orifice air valves.
Installation and Location
It is highly recommended that a basic review be made before selecting the appropriate air valves and determining their sizes and locations:
Typical installation locations:
One-way or check valves are liquid direction devices that allow one-directional flow in the pipeline.
Check valves have various uses such as:
There are various types of check valves:
- Swing-type check valves, check valves with top covers, check valves with a tilting disc, dual-leaf check valves, wafer type check valves, spring-loaded check valves, etc.
All one-directional valves are built from a basic combination of a body (straight or angular) connected to piping and to a one-way sealing mechanism. The valves are distinguished from one another by the structure of the body and the various sealing mechanisms.
The purpose of the various types of check valves is to provide solutions and adaptations for various applications.
The R&D, engineering and manufacturing divisions of A.R.I. worked together to develop a basket of check valves for a variety of applications. They meet the needs of designers, installers, users and maintenance personnel.
A.R.I. check valves are adapted for industry, wastewater, desalination, hot water, contaminated water, seawater, agricultural and gardening applications, potable water, water treatment systems, municipal lines and oil installations on offshore platforms.
Top-cover type check valves are designed to contend with aggressive environments and solids-laden liquids:
Characteristics of Industrial Air Valves
The main applications of the air valves according to the industrial field:
• Desalination – and other marine and brine environments.
• ACHV – hot water systems and INHIBITOR solutions.
