Specifications︰
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 mmstroke. 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:−5 ... +50 °C
• 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: Valve stem retracts, through-port opens
• Voltage at Y2: Valve stem extends, through-port closes
• No voltage at Y1 or Y2: Valve stem holds current position
Advantages︰
Connector S1 (under the cover, on the printed circuit board) can be repositioned to
change the flow characteristic of valves with a 5.5 mm stroke from “equal percentage” to
“linear”; in all cases the flow characteristic relates to the through-port of the valve.
• Connecting S1 to pins A and C produces an equal percentage flow characteristic
(factory setting), primarily for heating applications
• Connecting S1 to pins B and C produces a linear flow characteristic,
primarily for cooling applications
• For automatic operation, S1 must be connected either to pins A and C, or B and C,
depending on the required flow characteristic.
