Applications: Double Orifice automatic air vent valve is used in the industrial pipelines to release the air in the pipeline quickly, so as to improve the transmitting efficiency and prevent pipelines being broken and out of shape. Characteristics: 1. Release the air in the pipelines, reduce the resistant force and save energy. 2. Suck the air automatically and quickly so as to prevent the pipelines being broken while the backpressure is higher. 3. The air vent ability is better than the normal air vent valves 4. Stainless steel floating ball and supporting ring can make it reliable and can be used longer.  Double Orifices Automatic Air Vent Valve Specifications:  Suitable medium: water,sea water   Main material: grey iron, ductile Suitable temperature: ≤80ºC Nominal pressure: PN10/PN16 Nominal diameter: DN50-DN300mm Flange dimension: BS4504 ISO2531,ISO7005   Design of Double Orifices Automatic Air Vent Valve:   Face to face is according to ISO STANDARD   Flange drilled is according to DIN,BS,JIS,ANSI etc   Test of Double Orifices Automatic Air Vent Valve:  Working pressure PN10/PN16 Class125/150 Shell pressure PN15/PN24 300PSI Seat pressure PN11/PN17.6 200PSI MATERIALS OF MAIN PARTS: Name of parts Material of parts Body, gate grey iron/ductile iron/carbon steel Cover grey iron/ductile iron/carbon steel Float Stainless steel Stem Stainless steel Sealing ring Rubber
