Bermad - Model C15P - Combination Air Valve

BERMAD C15P is a high-quality combination air valve for a variety of networks and operating conditions. It reliefs 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, this valve provides excellent protection against air accumulation and vacuum formation, with improved sealing in low-pressure conditions.

Features & Benefits

• Straight flow body with large diameter automatic orifice: 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).
• Compact, simple, and reliable structure with full corrosion, chemical, and fertilizer-resistant parts: Lower maintenance and increased life span.
• Design in compliance with EN-1074/4 standard.
• Factory approval and Quality Control: Performance and specification tested and measured with a specialized test bench, including vacuum pressure conditions.
• Field-proven designed for use in irrigation applications with water quality such as river water, channel water, dam water or treated effluent with high reliability.

Additional Features & Accessories

• Service Port fitted with ¼” Plug (code P)
• Test point (code T)

Typical Applications

• Main Irrigation Networks: Protection against air accumulation and vacuum formation downstream of pumps, along supply lines, and at elevations in main irrigation networks
