This Appraisal is for a range of Bermad C70 metallic bodied combination (double orifice) air valves for water applications in sizes DN 50 to DN 200. This Issue 3 is to advise that Bermad Australia Pty Ltd is now fully owned by Bermad CS Ltd. The distribution arrangements for the range of valves have also been amended.
The valves, suitable for water applications in pump stations and pipelines, evacuate air during pipeline filling, allow release of air pockets from pressurized pipes and enable large volumes of air intake in the event of network draining.
The Bermad C70-SP air valve version incorporates an anti-slam device for surge protection.
The valves are available with pressure classification PN 16 or PN 35 with flanges to AS/NZS 4087 Figure B5 or B6, respectively. DN 50 valves are also available with a BSP threaded connection.
