A.R.I. Flow Control Accessories products

The R-20 series is a line of composite material, diaphragm - operated hydraulic control valves with a working pressure up to 10 bar. The valves are suitable for installation on water transmission, landscape and irrigation systems. The R-20 series has an innovative elliptic shaped diaphragm that integrates well with a wide variety of regulating control pilots, solenoids and control accessories.

The DG-10 combination air valve has the features of both an air release valve and an air & vacuum valve. The air release component of the combination air valve was 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 was 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-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. This valve will open to relieve negative pressures whenever water column separation occurs.

The D-020 Combination Air Valve combines an air & vacuum orifice and an air release orifice in a single body. The valve is specially designed to operate with liquids carrying solid particles such as wastewater and effluents. The combination air valve discharges air (gases) during the filling or charging of the system, admits air into the system while it is being emptied of liquid and releases accumulated air (gases) from the system while it is under pressure and operating. The valve’s unique design enables the separation of the liquid from the sealing mechanism and assures optimum working conditions.

The D-020 SB is a complete product package that combines the reliable and efficient properties of the A.R.I. D-020 combination air valve for wastewater with the added feature of a sub-surface valve that can be buried below ground. A specially designed horizontal sliding disc valve - situated at the base of the D-020 SB assembly - allows for the air valve disconnection and maintenance from ground level. This shut-off valve is equipped with a safety mechanism enabling disconnection and removal of the D-020 air valve from its sub-surface housing, even when the system is under pressure. Since service and maintenance operations of the unit are performed entirely from the surface, there is no need for safety considerations associated with confined space entry.
