Features and Benefits

• Sֺֺtraight flow body with large diameter automatic orifice: Higher than usual flow rates.
• Aֺֺerodynamic full-body kinetic shield: Prevents premature closing, without disturbing air intake or discharge.
• Dֺֺynamic sealing: Prevents leakage under low pressure conditions (1.5 psi; 0.1 bar).
• Tֺֺhe boss on the base can be tapped with a thread for pressure gauge connection, check point or test drain for air valve function.
• Tֺֺhreaded Side outlet (2”; DN50) for connection of Surge Protection (code SP) or Inflow prevention (code IP) devices.
• Cֺֺompact, simple and reliable structure with fully corrosion resistant internal parts; lower maintenance and increased life span.
• Dֺֺesign in compliance with functional standard and water service standards.
• Fֺֺactory approval and Quality Control: Performance and specification tested and measured with specialized test bench, including vacuum pressure conditions.

Additional Features & Accessories

• Sֺֺurge Protection (code SP) device: Smoother operation, preventing damage to the valve and the system.
• Iֺֺnflow Prevention (code IP) device: Prevents intake of atmospheric air in cases where this could lead to damaged pumps, required re-priming, or disruption of siphons.
• Sֺֺervice Ports fitted: ¹/8”;DN3 or ¼”;DN6 plug for pressure gauge connection, check point or test drain for air valve function.
• Eֺֺxtension with downwards outlet, only for inlet sizes 2-3”; DN50-80.

Typical Applications

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