C70 Combination Air Valve
BERMAD C70 is a high quality combination air valve for a variety of operating conditions applications such as pumping stations, deep well pumps, pipelines and water networks. It evacuates air during pipeline filling, allows efficient release of air pockets from pressurized pipes, and enables large volume air intake in the event of network draining. With its advanced aerodynamic design, double orifice and Surge Protection (Anti-slam / slow closing) device, this valve provides excellent protection against air accumulation, vacuum formation and pressure surges, with improved sealing in low pressure conditions. The valve minimizes water spraying during air release. The C70 technology minimizes water spray during air release and improves sealing in low pressure conditions. Fully WSAA appraised and accredited to AS4956, AS4020, AS4158 and AS4087.
FEATURES
- Straight flow body with nominal (equal) inlet and outlet size: Higher than usual flow rates.
- Aerodynamic full-body kinetic shield: Prevents premature closing without disturbing air intake or discharge.
- Dynamic sealing: Prevents leakage under low pressure conditions (1.5 psi; 0.1 bar).
- Minimizes water spraying during air release: Innovative 2-step function, automatic orifice (Patent Pending).
- Three optional outlets (sideways, downwards, circular surround mushroom configuration) that can swivel 360°:
