DAV-MP-2-KA Combination Air-Valve, Metallic-Shield

DAV-MP-2-KA Combination Air-Valve, Metallic-Shield


This valve has been designed for efficient discharge and intake of air in water pipelines, filtering systems, containers, and other places where confined air could impair the system’s operation.

The valve is designed for:

  • Discharge of high air-volumes during the initial filling of the systems
  • Introducing large quantities of air when the pipe drains, maintaining   atmospheric   pressure   in   the   pipe   and preventing collapse and cavitation damage to the conduits
  • Relieving  air  from  the  water-filled  system,  while  the network is pressurized

Features & Advantages

  • Leak-proof sealing at all conditions, including low system pressure.
  • The aerodynamic design of the float provides air flow at a very high velocity. The float does not close before the water has reached the valve.
  • Threaded outlet elbow allows various possibilities of drain connection.
  • The valve design contains a very limited number of parts, allowing easy dismantling for maintenance.

Technical Specifications

  • Operating pressure 0.1 bar / 1.5 psi to 25 bar / 360 psi
  • 2” Threaded/Flanged base - as per the customer’s choice
  • Cover material: Ductile Iron
  • Base Material: Ductile Iron
  • Internal parts: corrosion resistant, reinforced plastic materials and synthetic rubber
  • The valve allows the discharge of 450m3/h of air at a line pressure of 0.9 bar, when fully-open
