BON • O • METER

BON•O•METER
is a metering ball valve.
The solution developed integrate
the metering device inside the ball
in such a manner that:
The orifice and the ball form
  one piece only.
The delta pressure measurement
points (upstream and downstream
the orifice) are machined on the
valve outlets so that they can be
rotated by means of disconnecting
the bolts (body/outlets)
in accordance with the media characteristics (upper for gases
and down for liquids).
The engineering of the BON•O•METER
has been designed to achieve the metering results (in the most simple way) inside the ball valve, without
any change in the valve itself.
So, it is possible to maintain the cost and the features of the application
quite similar to a normal ball valve. That’s the aim of the BON•O•METER.
The ball is easily removable.
The ball valve used for the
BON•O•METER is TOPAZ design
