with 90° angle of rotation

SQK33.00

SQL33.0...

SQL83...

• SQK33.00 Operating voltage AC 230 V

• SQL33.0... Operating voltage AC 230 V

• SQL83.00 Operating voltage AC 24 V

• 3-position control signal

• Auxiliary switch and potentiometer for additional functions

• Nominal angle of rotation 90°

• Reversible electric motor

• For mounting on butterfly valves and slipper valves with ASK… mounting kit

• With manual adjuster and position indicator

Use

For use in heating, ventilation and air conditioning systems to operate Siemens butterfly

valves and three-port and four-port slipper valves (mixing valves), types K1i…,

VKF41…, VB… and VC... (see "Equipment combinations") and valves from other

manufacturers.

The actuators can be fitted with additional auxiliary switches and potentiometers

Functions If the actuator is driven by a 3-position signal from the controller, it generates a rotary motion which is transferred to the valve (butterfly, slipper valve, three-port or four-port mixing valve). Direction of rotation of the actuator on delivery: • Voltage at Y1 = Clockwise rotation • Voltage at Y2 = Anti-clockwise rotation • No voltage = No rotation; actuator fixed in relevant position . . The direction of rotation can be reversed if required. Extending the actuator functions • The SQK33.

Mounting Mounting instructions are enclosed with the mounting kit. The valve, actuator and mounting kit are packed separately. The valve and actuator can be assembled easily on site. There is no need for special tools or calibration. Take care to install the valve the right way up. Refer to the mounting instructions for the valve concerned (butterfly or slipper valves). Orientation . . . . . . . . . . .
PAGE 6
Setting the angle of rotation The angle of rotation is factory-set to 90°. However, the angle can be changed to between 70° and 180°. This may be necessary when using non-Siemens valves. Special notes on this subject will be found in the mounting instructions for the ASK40 and ASK41 (mounting kits for non-Siemens valves). Maintenance Warning ! Disposal The actuators require no maintenance.
