) at a differential pres-
sure of 100 kPa (1 bar)
Function / Mechanical design
When the actuator is driven by a 3-position positioning 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 without mounted actuator (NO).
∂ Voltage at Y1 / Q1: Stem retracts ⇓ Valve opens
∂ Voltage at Y2 / Q2: Stem extends ⇓ Valve closes
∂ No voltage at
Y1 / Q1 and Y2 / Q2: 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 switching off in the event of overload and
in stroke end positions
∂ Parallel operation of up to 6 actuators SSA31.04
