nBEMimD | Irrigation AUTOMATIC AIR VALVE Model A72 BERMAD A72 is an automatic air release valve that allows efficient release of air pockets from pressurized pipe lines. This valve provides excellent protection against air accumulation with improved sealing in low pressure conditions. A72 Air Valve is manufactured for Bermad by Dogus Vana. Features & Benefits ■ Efficient release of air pockets from pressurized pipe lines. ■ Prevents leakage under low pressure conditions (3 psi; 0.2 bar). ■ Compact, simple and reliable structure with fully corrosion resistant parts: Lower maintenance and increased life span. ■ Factory approval and Quality Control. Inlet Connections ■ Inlets: female threaded 1"; DN25 Typical Applications ■ Pipelines: Protection against air accumulation in high points and long horizontal lines. ■ In proximity to control valves and water meters: Prevention of inaccurate pressure regulation and biased readings due to air existence in these devices. ■ Materials ■ Body: Ductile Iron, Stainless Steel 316, Cast Steel (WCB) ■ Automatic Orifice: Stainless Steel 316 ■ Float Assembly: Polypropylene ■ Elastomers: NBR Operational Data ■ Pressure Rating: 250 psi; ISO PN16, 400 psi; ISO PN25, 600 psi; ISO PN40, 900 psi; ISO PN63 ■ Minimum operating pressure: 3 psi; 0.2 bar ■ Maximum operating pressure: 250 psi; 16 bar, 400 psi; 25 bar, 600 psi; 40 bar, 900 psi; 63 bar ■ Media and operating temperature: Water, 33-140°F; 1-80°C Orifice Specifications Automatic Orifice Area Inlet Sizes 250 psi 400 psi 600 psi 900 psi PN16 PN25 PN40 PN63 A72 is manufactured for BERMAD by a 3rd party All images in this catalog are for illustrati
