Bermad WW-C30-P-SP Combination PN16 Air Release Valve



Bermad WW-C30-P-SP Combination PN16 Air Release Valve with Surge Protection

The Bermad C30-P-SP is a triple function combination air valve with an inbuilt surge protection feature. The valve controls air discharge to avoid the valve slamming closed, an incident which has the potential to generate water hammer.

These valves are used at end of pipelines, sectional pipeline isolation valves, pumping stations, or along a pipeline where column separation can occur. The valves supplied in Australia are full certified for drinking water to approvals AS4956 & AS4020 and WSAA appraised


  • 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).
  • The boss on the base can be tapped with a thread for pressure gauge connection, check point or test drain for air valve function.
  • Threaded Side outlet (2”; DN50) for connection of Surge
  • Protection (code SP) or Inflow prevention (code IP) devices.
  • Compact, simple and reliable structure with fully corrosionresistant internal parts; lower maintenance and increased life span.
  • Design in compliance with functional standard and water service standards.
  • Factory approval and Quality Control: Performance and specification tested and measured with specialized test bench, including vacuum pressure conditions.


  • Pressure Rating: 230 psi; ISO PN16
  • Minimum operating pressure: 1.5 psi; 0.1 bar
  • Maximum operating pressure: 230 psi; 16 bar
  • Media and operating temperature: Water, 33-140°F; 1-60°
