Use
For Siemens PICV: VPI46.., VPP46.., VQI46.. and VQP46..
● In ventilation and air conditioning plants for control on the water side and automatic
hydraulic balancing of terminal units, such as fan coils, induction units, and in heat
exchangers for heating or cooling
● In heating zones like self-contained heating systems, apartments, individual rooms, etc.
● For closed circuits
Technical design
The actuator opens the valve electrically. It incorporates an electric motor and gear
mechanism. The maximum stroke is limited mechanically (valve seat). No motor power
consumption in fully open and closed position. The actuator is connected with a 0.8 m cable,
which is an integral part of it. The actuator can open or close the valve via controller
(thermostat) output signal.
2-position SPST control signal
The actuator requires an on/off controller, typically a room thermostat.
Voltage at Y:
Stem retracts
Valve opens
No voltage at Y:
Stem extends
Valve closes
CAUTION
Do not operate the SUE21P actuators in a 3-position control mode!
LED operating mode display, example of SUE21P:
4830Z02
Voltage on Y: LED is lit
No voltage on Y: LED is off at end position
The LED is lit when the actuator stem protrudes, retracts, or the valve fully opens. The LED
goes out when the actuator stem protrudes to the valve’s fully closed position.
