Detail Electric Actuators For Valves SQS35 65
? 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
? Spring return actuators with position indication and without manual
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
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
Advantages0 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.
