To ensure trouble-free operation of third-party valves with
the SSP… actuator, the valves must satisfy the following
requirements:
∂ Threaded connections with coupling nut M30 x 1.5
∂ Nominal force F ≤ 160 N
∂ Dimension x (with valve fully open) x > 9.0 mm
∂ Dimension y (with valve fully closed) y ′ 14.5 mm

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 without actuator (NC).
∂ Voltage at Y1: Stem extends: Valve opens
∂ Voltage at Y2: Stem retracts: Valve closes
∂ No voltage at Y1 or 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…P47… is fully closed (A ↑ AB).
∂ When power supply is removed, the actuator maintains its current position.
∂ Position indication
∂ 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 SSP31…, 24 SSP81… and 10
SSP61... 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 cable available
