Definition
Flow control
Vnom is the maximum possible flow.
Vmax is the maximum flow rate which has been set with the greatest positioning
signal. Vmax can be set between 30% and 100% of Vnom.
Vmin 0% (non-variable).

Creep flow suppression
Given the very low flow speed in the opening point, this can no longer be measured by
the sensor within the required tolerance. This range is overridden electronically.
Opening valve
The valve remains closed until the volumetric flow required by the positioning signal Y
corresponds to 1% of Vnom. The control along the valve characteristic curve is active
after this value has been exceeded.
Closing valve
The control along the valve characteristic curve is active up to the required flow rate of
1% of Vnom. Once the level falls below this value, the flow rate is maintained at 1% of
Vnom. If the level falls below the flow rate of 0.5% of Vnom required by the reference
variable Y, then the valve will close.

Converter for sensors
Connection option for a sensor (active sensor or switching contact). The MP actuator
serves as an analogue/digital converter for the transmission of the sensor signal via
MP-Bus to the higher level system.
Configurable actuators
The factory settings cover the most common applications. Single parameters can be
modified with the Belimo Service Tools MFT-P or ZTH AP.
Positioning signal inversion
This can be inverted in cases of control with an analogue positioning signal. The
inversion causes the reversal of the standard behaviour, i.e. at a positioning signal of
0%, regulation is to max, and the valve is closed at a positioning signal of 100%.
Hydraulic balancing
With the Belimo tools, the maximum flow rate (equivalent to 100% requirement) can
be adjusted on-site, simply and reliably, in a few steps. If the device is integrated in the
management system, then the balancing can be handled directly by the management
system.
Manual override
Manual override with push-button possible (the gear is disengaged for as long as the
button is pressed or remains locked).
High functional reliability
The actuator is overload protected, requires no limit switches and automatically stops
when the end stop is reached.
