www.belimo.com
• The actuator has been designed for use in stationary heating, ventilation and air conditioning
systems and is not allowed to be used outside the specified field of application, especially in
aircraft or in any other airborne means of transport.
• Caution: Power supply voltage!
• It may only be installed by suitably trained personnel. Any legal regulations or regulations
issued by authorities must be observed during assembly.
• The device does not contain any parts that can be replaced or repaired by the user.
• The device contains electrical and electronic components and is not allowed to be disposed
of as household refuse. All locally valid regulations and requirements must be observed.

NV230-3(-T)
Linear actuator for globe valves, AC 230 V, 1000 N
Product features
Mode of operation
Installation on BELIMO valves
The actuator is activated with a 3-point signal.
If a combination of actuator and BELIMO globe valve is ordered, then one UNV-002 bracket is
included in the scope of delivery.

l
b
a
l
i

v
a
If an actuator is ordered without Belimo globe valve, then the UNV-002 bracket (see «Accessories»)
must also be ordered.
Installation on third-party valves
Prior to installation on a third-party valve, a suitable bracket UNV-.. (see «Accessories») must
first be screwed to the actuator. The adapter set integrated therein is comprised of a valve neck
adapter and a valve stem adapter. The valve neck adapter, together with the clamping strap on
the bracket, makes possible simple attachment on the neck of the valve. The valve stem adapter
is mounted on the valve stem. The linear spindle can be coupled semi-automatically to the valve
stem with the valve stem coupling.
The actuator can be rotated by 360° on the valve neck.

Retrofit actuators NV.. -R are also available which are equipped with a Retrofit bracket and
which can be used with corresponding ZNV-.. (adapter set) for valves from a wide array of
manufacturers.

Functional reliability
Position indication
Combination valve/actuator
The stroke can be adjusted in a voltage-free state by using a hexagon socket screw key (5 mm),
which is plugged into the actuator at the top. If the hexagon socket screw key is turned in a
clockwise direction, then the actuator spindle will extend from the actuator housing (pushing) and
maintain the position until a nominal voltage is applied (the controller has first priority).
The actuator is protected against short circuits, polarity reversal and overloading.
The stroke is indicated mechanically on the bracket. The stroke range adjusts itself automatically.
Refer to the valve documentation for suitable valves, their permitted media temperatures and
closing pressures.

Functions
Alignment of the operating elements
S1.1
The terminals for the cable connection and the
operating element S1 are located under the
cover of the actuator.
By setting slide switch S1 it is possible to
configure the actuator very simply on site to
suit actual requirements.
