• Electric actuator, no maintenance required
• Reversible synchronous motor
• Anti-locking gear mechanism
• SQS35.50, SQS35.53, SQS65.5 have spring return function to DIN 32730
• Load-dependent switch-off in stroke limit positions
• Selectable flow characteristic:equal percentage or linear for SQS65... actuators in
conjunction with valve types VVG44..., VVI52... and VXG44...
• Directly impacting manual adjustment for all non-spring-return actuators: SQS35.00,
SQS35.03, SQS65, SQS65.2, SQS85...
• Position indicator on all SQS35..., SQS65..., SQS85... actuators
• Accommodation for auxiliary switch type ASC9.6 on the SQS35.00, SQS35.03,
SQS85.00 and SQS85.03 actuators. An auxiliary switch ( not the ASC9.6) is built in
as standard in actuator types SQS35.50 and SQS35.53 actuators.
