Brand: Bermad
Category: Air Valves, Combination Air Valves
Size Range:

50mm

Connection:

Threaded Male BSPT

Product Description

BERMAD C35P is a high-quality combination air valve for a variety of water 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

  • Water networks: Protection against air accumulation and vacuum formation at elevations, slope change points, and road/river crossings.
