Bermad Air Release Valves

The new line of BERMAD air valves includes plastic air valves ranging from ¾” - 2” for a variety of water, sewage and waste water pipeline and networks. These valves offer:

Bermad logo
  • Higher flow rates - Advanced aerodynamic design with a straight-flow body, nominal inlets and outlets allowing higher than ever before flow rates.
  • Leakage reduction - BERMAD Air Valves operate with a minimal operating pressure (0.1bar/1.5psi) based on dynamic sealing properties (no dribbling)
  • Minimal spray effect - Minimizing the spray effect during automatic air release to negligible quantities.
  • Built-in surge protection (anti-slam feature) - Responds to the approachof high velocity water column by slow air relief, preventing damage to the valve and to the entire system.
  • Versatile design for easy installation - Three types of outlets - downwards, sideways (that can swivel 360°) and circular.
  • Reliable Structure - All parts are fully resistant to corrosion – Lower maintenance and increased life span.

Bermad K10 - Kinetic Air Valves

Bermad K10 

Kinetic Air Valves 

  • Straight flow body with large diameter orifice – High flow rates.
  • Aerodynamic full-body kinetic shield – Prevents premature closing without disturbing air intake or discharge.
  • Dynamic sealing – Prevents leakage during operation even under low pressure conditions (0.1 bar).
  • The boss on the base can be tapped with a thread for pressure gauge connection, check point or test drain for air valve function.
  • Compact, simple and reliable structure whose parts are fully corrosion, chemical and fertilizer resistant – Lower maintenance and increased life span.
  • Factory approval and Quality Control – Performance and specification tested and measured with specialized test bench, including vacuum pressure conditions.
  • PN10
