OEM Singles Orifice Air Release Valve Irrigation System PN16

Singles Orifice Air Valve Threaded

1. PRODUCT PROFILE

Single orifice air valve is one type of single ball air release valve with flange ends.Air valve is one important exhaust valve in the long big piping transport, which often fitted at the highest point on a pipeline to continually release unwanted air during system operation to protect against unwanted surges and maintain system efficiency.

Single orifice air valve can remove the air existed in the pipe more flexible, preventing of the pressure fluctuation or other damages in the piping system. Single orifice air valve is applicable especially to the main water pipes, sewage pipes and deep well pumps piping system. The bore leading to the flange base shall be in accordance to the size of the main pipeline and the
expected accumulation of air.Prosper Flow can manufacture the single orifice air valve according to standard of BS EN1074-4:2000, BS5163:2004 with sizes of 3/4”~ 8” (DN20 ~ DN200mm).

2. FEATURES

· Discharge air more flexible

· Preventing of the water hammer

· Safer self-protection

· Small volume, light weight, small exhaust flow

· Single Orifice ARV is installed on the pipe with a flange, releases the air recevied from its flange connnection through the orifice located above the float part. When the air release is completed, the float travels upside with the water force and closes the orifice outlet, thus preventing the leakage of water.

· The biggest problem of Single Orifice Air Relaese Valve is the ARV blockage. For this reason, ARV’s on the line must be checked at certain intervals.

· While the pipeline is taken into service, it enables the air accumulation and discharges out of the system.

Single Orifice Air Valve

Single Orifice Air Valve is used in independent heating systems, central heating systems, heating boilers, central air conditioning, floor heating and solar heating systems and other pipeline exhaust. Because there is usually a certain amount of air dissolved in water, and the solubility of air varies with temperature Increase and decrease, so that the gas gradually separates from the water in the process of water circulation, and gradually gathers together to form large bubbles or even air columns.Because of the supplement of water, gas is often generated.

Anhui Prosper Flow Technology Co., Ltd. is located in Tongling City, Anhui Province, a famous ductile iron valve production base   in China.Such as the Giant AVK Valve and TALIS Spain,who all buy castings here.
