Use
● For 2-way and 3-way Powermite 599 MZ Series globe valves, 599-01100 - 599-01139
● Typically in chilled ceiling, VAV, unit ventilators, fan coil unit and other terminal unit ap-
plications
● Max.10 units of SSB161.05U can operate in parallel, provided the controller output
suffices.
Technical design
When the actuator is driven by DC 0…10 V positioning signal, it produces a stroke, which is
transmitted to the valve stem. This is converted to mechanical stroke which controls the
position of valve stem.
If not specifically stated, the description of operation in this document applies to valve
versions that are fully closed when valve stem is extended / no actuator is mounted.
DC 0...10 V control signal
● The valve opens / closes in proportion to the
control signal at Y.
● At DC 0 V, the actuator stem is retracted, the
normally closed valve is fully closed and the
normally open valve is fully open.
● When no power is supplied, the actuator maintains
its current position.
Y = Control signal Y [V]
H = Percentage of calibrated valve stroke
