Kinetic 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:
•t Releasing high volumes of air during the initial filling of
the system
•t Introducing large quantities of air when the pipe drains,
maintaining atmospheric pressures in the pipe and
preventing collapse and cavitation damage to the conduits
Properties:
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 will 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.
Operation:
•t Introduction
of air into the pipeline when the internal
pressure is sub-atmospheric. The pressure difference and
the gravity, force the float to drop to “opened” position,
allowing large volumes of air to flow into the pipe.
Technical Specifications:
•t Operating pressure 0.2 to 25 bar
•t 1” BSP or NPT threaded base •t

Cover material: Cast Iron
Base Material: Brass
Internal parts: corrosion resistant, reinforced plastic
materials and synthetic rubber
The valve allows the discharge of over 220m3/h of air at a
pipe pressure of 1.0 bar, when fully-open
The DAV-MP-K valve has two modes of operation:
•t Discharge of large quantities of air at a high flow velocity
when the conduit is being filled. When the water arrives to
the valve, the float rises up and closes the outlet.
Principle of operation:
Pipe is full of water
Pipe is aerated
