  • Air Valves for water
  • Description: 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.

Company

A.R.I Flow Control Accessories Ltd., established in 1970,  is one of the leading companies specializing in protection solutions for water systems; protection from pressure transients and entrapped air in pipelines.

These are the main causes for pipe burst, collapse and fracture and result in water losses due to leaks and contamination due to release of pathogens.

Founded in 1970, A.R.I Flow Control Accessories Ltd. has developed a wide range of products and special software for various applications in water supply (municipal and domestic), sewage, industry, agriculture and landscaping.

A.R.I Flow Control Accessories Ltd. has an application engineering department which provides surge analysis and protection solutions for water systems.

A.R.I Flow Control Accessories Ltd. is constantly responding to the demands of an ever-changing market through an on-going development of new products.

The company has established its reputation for advanced, high quality and durable products (mainly air valves and check valves), as well as for dedicated technical support services. All valve models manufactured by A.R.I Flow Control Accessories Ltd. are standard but can also be custom-engineered to

meet specific requirements.In the recent years, the company has entered the ongoing worldwide effort for water saving management and developed the UFR (Unmeasured Flow Reducer) for more accurate water measurement and reduction in non- revenue water losses.

A.R.I Flow Control Accessories Ltd. has established its high quality assurance standards in compliance with ISO 9001 and ISO 14001.

A.R.I Flow Control Accessories Ltd. products are made of various metals and non-ferrous materials, varying in size from 1/2” (12mm) to 40” (1000mm) and in working pressures from 0.2 bar (3 psi) up to 100bar (1400 psi).

A.R.I Flow Control Accessories Ltd. products are manufactured in accordance with leading international standards.

The valves are designed with a special emphasis on advanced and innovative design: top performance,

lightweight corrosion-resistant materials, minimum maintenance, durability and modern appearance.

Several patents have been registered worldwide.

UFR - UnmeasuredFlowReducer

The innovative Unmeasured-Flow Reducer (UFR) is a patented smart and simple solution, installed in the domestic water supply line (In-Line), adjacent to the water meter. At low flow rates, the UFRchanges the flow regime to batches that the water meter can measure.

UFR - Operating Principles

The UFRbegins working when there are low flow rates, below Qmin.

The UFRregulates the water flow so there is no water flow at all through the UFRpart of the time, while the rest of the time, the flow is high enough to be measured. A change in the flow discipline at low flow rates allows the existing water meter to measure those low flow rates it could not measure before.

When the flow rate increases above Qmin, the UFRremains open so that it does not interfere with normal measurements.

THE PROBLEM - Apparent (commercial) water losses

A major cause for apparent water losses is the fact that domestic water meters have difficulty in measuring very low flow rates mainly below Qmin.

The minimum flow rate (Qmin), where an accuracy of ±5% is required by the appropriate ISO standard, for small domestic water meters (Qn 1.5) is 30 l/h for class B water meters, 15 l/h for class C water meters and 11.25 l/h for class D water meters.Loss of income due to the under-registration of water meters at low flow rates

Under-registration of low flow rates is the main reason for apparent water losses and it can count for more than 5% of the total water sold to users by the municipality. For old water meters, Qmin is higher and apparent water losses can be more than 10%.

Main reasons for leaks and low flow rates that cause under-registration of the water meter:

  • Dripping or improperly closed faucet.
  • Leaks in toilet tank seals.
  • Very low flow rates at the end of the filling cycle of toilet tanks and water storage tanks.
  • Pipework leakages downstream of the water meter. 

Advantages of the UFR

  • Reduces unmeasured flow, cuts down apparent losses.
  • Substantially increases the income of the Water Authority, up to 10%.
  • The UFR is a high quality check valve preventing backflow and main pipe contamination.
  • When water is billed in a block of flats according to the domestic water meter plus the mean difference between the domestic water meters and the main water meter, the UFR can make the billing fairer.
  • Turns apparent water losses into revenue water.
  • Reduces measurement differences between the main water meter and domestic water meters.
