Customized Single Orifice Automatic Release Valve Air Valve For Water Supply

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

· Ductile iron body, flanged connection according to EN 1092-2. Float part made of polyethylene which can be replaced easily.

·If the air is not discharged in water transmission and water network when on duty, air is collected in certain areas and may cause the danger of stopping the waterflow. This danger is increased with the congestion, and causing the pipeline to explode and major damages.

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.
