ADCA AUTOMATIC AIR AND GAS VENTS FOR LIQUID SYSTEMS AE31.2 (Carbon steel 1" x 1/2"; DN 25 x 15) DESCRIPTION The AE31.2 is a series of automatic vents designed to remove air or gases from water and other liquid systems, without requiring any external source of energy. They are capable of handling significant loads during start-up while still being able to discharge smaller loads in continuous modulating operation with one single orifice. These ball float type vents are manufactured in carbon steel, available with soft sealing, and can be used in combination with other air elimination and separation systems or directly applied at high points in the pipelines. MAIN FEATURES Suitable for start-up and continuous operation with one single orifice. Allow fast and easy inline maintenance. Corrosion resistant internal parts. No balancing pipe required. OPTIONS: Metal to metal sealing. Threaded connection on cover, closed with plug. HVV – Hand vent valve. Cold, hot and superheated water or other liquids compatible with the construction. AVAILABLE MODELS: Female threaded ISO 7 Rp or NPT. Flanged EN 1092-1 PN 40. Flanged ASME B16.5 Class 150 or 300. Socket weld (SW) ASME B16.11. Vertical installation. It must be installed absolutely vertically at the points in the plant where the air tends to collect. See IMI – Installation and maintenance instructions.

ADCA FLOW RATE CAPACITY (NL/min) DIFFERENTIAL PRESSURE (bar) Values shown refer to capacities of air discharge at 15 ºC, under average atmospheric pressure (1013 mbar). If the temperature of the air differs from 15 ºC, the discharge capacity can be corrected by multiplying it by: temperature in ºC. It may be assumed that the temperature of the air is equal to the temperature of the water. * As standard, in versions with EN flanges or female ISO 7 Rp threads, these connections are female threaded ISO 228. In versions with ASME flanges, female NPT threads or SW, these connections are female...
