This system uses an electronic fuel balancing valve
for fine-tuning the fuel delivery to each cylinder to achieve near perfect balance for all operating conditions of the unit.
In this case, there is only one balancing valve
at the air-coil, so the pressure drop under design conditions may be smaller than in Fig 2 and furthermore it will decrease as the thermal capacity is turned down.
KSB, the Loughborough based international pump manufacturer, has launched a new balancing valve
, the BOA Control IMS.
The change in pressure shifts the balancing valve
over a relief port or a pressure port, depending on whether the pressure in the lift cylinder has risen or fallen.
The [C.sub.v] factor on a coil or calibrated balancing valve
(CBV) will be fixed.

'We are currently the world leader in manual balancing technology and the acquisition of Flow Design enables us to exploit the opportunities within the rapidly growing automatic balancing valve
Another type of balancing valve
uses a flow sensor to measure the flow rate, plus some type of throttling valve, impeller trimming, or a variable speed drive to limit the maximum flow rate.
