Used in conjunction with valve types VVG44..., VVI52... or VXG44..., these actuators
generate a linear flow characteristic.
In conjunction with valve types VVG44..., VVI52... or VXG44... these actuators generate
an equal-percentage flow characteristic (factory-setting) via the integrated electronic
assembly. The flow characteristic can be changed to "linear" by repositioning the
connector.

applications described applies only to the Landis & Staefa valves listed in this data
sheet under "Compatibility".
The use of type SQS... actuators in conjunction with third-party valves invalidates
all claims under the Landis & Staefa warranty.
When servicing the valve: switch OFF the pump and power supply, close the main shut-
off valve in the pipework, release pressure in the pipes and allow them to cool down
completely. If necessary, disconnect electrical connections from terminals.
The actuator must be correctly fitted to the valve before re-commissioning.
