Irrigation

BERMAD C30 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 device (optional), this valve provides excellent protection against air accumulation and prevents vacuum formation, with improved sealing in low pressure conditions.

Straight flow body with nominal (equal) inlet and outlet size: Higher than usual flow rates.
Dynamic Sealing: Prevents leakage under low pressure conditions (1.5 psi; 0.1 bar).
Surge Protection (code SP) as standard feature for 2”; DN50. The kinetic orifice is partially closed during the second stage of the air relief, preventing damage to the air valve and the system.
Compact and simple structure with fully corrosion resistant internal parts: Lower maintenance and increased life span.
Certified to functional standards: EN-1074/4 (Europe), AENOR (Spain).
Designed in compliance with AWWA C512 (USA).
Certified to drinking water standards: WRAS (UK), ACS (France), NSF-ANSI-CAN 61 and NSF-ANSI 372 (USA), PUB SS 375 and SS 270 (Singapore).
Factory approval and Quality Control: Performance and specification tested and measured with specialized test bench, including vacuum pressure conditions.

Typical Applications

Pipelines: Protection against air accumulation and vacuum formation at elevations, slope change points and road / river crossings.
Water networks: Protection against air accumulation and vacuum formation.
In proximity to control valves and water meters: Prevention of inaccurate pressure regulation and biased readings due to air existence in these devices.
