Piping
The valves should be mounted in a weather-protected area in a location that is within
the ambient limits of the actuator. Allow sufficient room for valve with actuator and
for service. Please allow 12” for complete actuator/linkage removal. The G2(S) and
G3(D) preferred mounting position of the valve is with the valve stem vertical above
the valve body, for maximum life. However, the assemblies can be mounted with the
valve stem vertical or horizontal in relation to the pipe. The actuators should never be
mounted underneath the valve, as condensation can build up and result in a failure of
the actuators. Do not reverse flow direction.
Stem Up- Open B to AB
Note: Flow B to A travels through center of plug
(as shown).

On/Off, Floating Point, Electronic Fail-Safe, Linear, 24 V
Application
Fail-safe for On/Off and floating control types of globe valves in HVAC steam and
hydronic systems.
Actuator sizing will be dictated by the valve size selection. All valve selections should
be done in accordance with the flow parameters and system specifications. The
actuator is mounted directly to the globe valve bonnet by means of its universal clamp
and collar.
The actuator operates in response to a 24 volt signal being applied from an electronic
controller or positioner.
Operation
The actuator is not provided with and does not require any limit switches, but is
electronically protected against overload. The LV series provides 15 mm of downward
travel and a visual indicator indicates position of the actuator. When reaching the valve
end position, the actuator automatically stops. The gears can be manually disengaged
with a button on the actuator cover.
The LVK… series actuators use a sensorless brushless DC motor. The ASIC inside
monitors and controls the actuator’s rotation and provides a digital rotation sensing
(DRS) function to prevent damage to the actuator in a stall condition. Power
consumption is reduced in holding mode.

Typical Specification
Wiring Diagrams
On/Off, floating control globe valve actuators shall be electronic and direct coupled to
the globe valve bonnet via an integrated linkage, which requires no secondary linkage
and be capable of mounting to valves ½” to 2” in size. Actuators must provide control
in response to a control input from an electronic controller or positioner. Actuators shall
have brushless DC motor technology and be protected from overload at all angles of
rotation. Actuators shall have reversing switch and manual override on the cover. Run
time shall be constant and independent of torque. Actuators shall be cULus listed,
have a 5-year warranty, and be manufactured under ISO 9001 International Quality
Control Standards. Actuators shall be as manufactured by Belimo.
CAUTION Equipment Damage!
Actuators may be connected in parallel. Power consumption and input
impedance must be observed.
2
Control signal may be pulsed from either the Hot (Source) or Common
(Sink) 24 VAC line.
8
For triac sink the common connection from the actuator
must be connected to the hot connection of the controller. Contact closures
A & B also can be triacs. A & B should both be closed for the triac source
and open for triac sink.
9
Actuators with plenum cable do not have numbers; use color codes instead.
188
Meets cULus or UL and CSA Standard requirements without the
need of an electrical ground connection.
WARNING
G Live Electrical Components!
During installation, testing, servicing and troubleshooting of this product, it may be
necessary to work with live electrical components. Have a qualified licensed electrician or other
individual who has been properly trained in handling live electrical components perform these
tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.
