To ensure trouble-free operation of third-party valves with the
SSA.. actuator, the valves must satisfy the following
requirements:
· Threaded connections with coupling nut M30 x 1.5
· Nominal force F £ 100 N
· Dimension x x > 9.0 mm
· Dimension y 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 open when de-energized (NO).
· Voltage at Y1: Stem retracts Valve opens
· Voltage at Y2: Stem extends 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 is fully closed (A à AB).
· When power supply is removed, the actuator
maintains its current position.
