BERMAD C70 is a high quality combination air valve for a variety of water networks and operating conditions. 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 again air accumulation,vacuum formation and pressure surges, with improved sealing in low pressure conditions. The valve minimizes water spraying during air release.

Features & Benefits

■Sֺtraight flow body with nominal (equal) inlet and outlet size: Higher than usual flow rates.

■Aֺerodynamic full-body kinetic shield: Prevents premature closing without disturbing air intake or discharge.

■Dֺynamic sealing: Prevents leakage under low pressure conditions (1.5 psi; 0.1 bar).

■Mֺinimizes water spraying during air release: Innovative 2-step function, automatic orifice (Patent Pending).

■Tֺhree optional outlets (sideways, downwards, circularsurround mushroom configuration) that can swivel 360°: Easy to

install in a variety of site conditions.

■Cֺompact, simple, robust and reliable structure with fully corrosion-resistant parts: Lower maintenance and increased

life span.

■Dֺesigned in compliance with functional standards and water service standards.

■Fֺactory approval and Quality Control: Performance and specification tested and measured with specialized test bench, including vacuum pressure conditions.

Additional Features & Accessories

■Bֺuilt in Adjustable Surge Protection (anti-slam): Smoother operation, preventing damage to the valve and the system.

The conditions for partially closing the kinetic orifice (the“switching value”) can be adjusted according to the specific system requirements (C70-SP, C70-AC, C70-AS).

■Iֺnflow Prevention: Prevents intake of atmospheric air in cases where this could lead to damaged pumps, required repriming,or disruption of siphons; prevents intake   of flood water or contaminated water into potable water networks (C70-IP).

■Sֺervice Port fitted with ¼”; DN6 plug (codes P, U)
