DAV-MP-1-KA Combination Air-Valve, Metallic-Shield

DAV-MP-1-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
  • 1” BSP or NPT threaded base - as per the customer’s choice
  • Cover material: Cast Iron
  • Base Material: Brass
  • Internal parts: corrosion resistant, reinforced plastic materials and synthetic rubber
  • At pipe pressure of 0.5 bar / 7 psi:
  • The 2”/50mm valve allows the discharge of 260 m3/h / 153 CFM of air
  • The 1”/25mm valve allows the discharge of 60 m3/h / 35 CFM of air
