Data Sheet for Product

Function / mechanical design
When the actuator is driven by DC 0…10 V control voltage or by a 3-position signal, it
produces a stroke which is transmitted to the valve stem.
The description of operation in this document applies to the valve versions which are
fully closed when de-energized (NC valves).
• Voltage at Y1: Stem extends Valve opens
• Voltage at Y2: Stem retracts Valve closes
• No voltage at Y1 and Y2: Actuator maintains its current position
• The valve opens / closes in proportion to the control signal at Y.
• At DC 0 V, the valve V..P45.. is fully closed (A → AB).
• When power supply is removed, the actuator maintains its current position.
• Plastic housing
• Locking-proof, maintenance-free gear train
• Manual override with hexagonal socket wrench 3 mm
• Reduced power consumption in the holding positions
• Load-dependent switch-off in the event of overload and in
stroke end positions
• Parallel operation of 6 SSB31.., 24 SSB81.. and 10 SSB61..
possible, provided the controllers’ output is sufficient
• Terminal block connectors for customer made cables
available
(only for use with AC 24 V and AC / DC 24 V actuators)
• Connecting cables with AC 24 V and AC 230 V connectors
cannot be mixed up
• Halogen-free cables available
