Electric actuators

for valves with

a 5.5 mm stroke

SQS35.50, SQS35.53

SQS65.5

with spring return / without manual adjustment

Electric actuators

• SQS35... AC 230 V operating voltage, 3-position control signal

• SQS85...AC 24 V operating voltage, 3-position control signal

• SQS65... AC 24 V operating voltage, DC 0 ...10 V or DC 2 ... 10 V control signal

• Positioning force 400 N

• Stroke 5.5 mm

• For direct mounting on valves, without adjustment

• Optional auxiliary switch for additional functions with SQS35.00, SQS35.03,

SQS85.00 and SQS85.03

• Choice of actuators with or without spring return function to DIN 32 730

• Non-spring return actuators with position indication and with manual

adjustment

• Spring return actuators with position indication and without manual

adjustment

Used to operate 2-port and 3-port valves with a 5.5 mm stroke. For valve types VVG44...,

VVG55..., VVP45..., VMP43..., VMP44..., VMP45..., VXG44..., VXP45..., VVI52...

• Area of application in accordance with IEC 721-3-3 Class 3K5

• Ambient temperatures:

• Temperature of medium in the connected valve:+2 ...+130 °C

• The use of mounting kit ASK30 enables the following valves with a 4mm or 5.5 mm

stroke to be operated: X3i..., VVG45..., VXG45..., VXG46... and VVI51...

The reversible synchronous motor is driven with a 3-position control signal (SQS35...

and SQS85...) or a proportional DC 0...10 V (SQS65, SQS65.5) or DC 2...10 V

(SQS65.2) control signal. The corresponding stroke is generated via an anti-locking

gear mechanism.

3-position control at terminals Y1 or Y2:

• Voltage at Y1:

• Voltage at Y2:

• No voltage at Y1 or Y2: Valve stem holds current position
