General information
1.1
Scope of these instructions
The PAW valve actuators SR2 are used as electric drives for PAW mixing valves (nominal
diameter DN 20) as well as drives for switch valves (on/off controls). The actuators can be
used as drives for standard controllers.
1.2
Designated use
The PAW valve actuators SR2 may only be used taking into consideration the technical
limit values indicated in these instructions.
Improper usage of the valve actuators excludes any liability claims.
The valve actuators can be used as accessory for PAW heating fitting groups.
This product complies with the relevant directives and is therefore labelled with the CE mark.
The Declaration of Conformity is available upon request. Please contact the manufacturer.
Only use PAW accessory with the PAW valve actuators.
The wrapping materials are made of recyclable materials and can be disposed of

Product description
The PAW valve actuators SR2 can be easily attached to the mixing valve with the halting
technique. The installation is carried out by means of two stop bolts which secure the
housing additionally against distort and which are part of the delivery.
2.1
Function
The rotation angle (adjustment range) is limited to 90°. When the actuator gets to an end
position it is switched off by means of the integrated limit switches. The actuator is then at
zero current. The actuator can be put into manual mode by pressing the rotary handle (position
indicator). When pressing the handle of the actuator the gears are disengaged and the mixing
valve can be adjusted to any position.
A blue/red coloured scale is stuck behind/under the rotary handle to indicate the position of
the mixing valve. The actuator is delivered in the left end position. The scale is prepared for the
operation "flow on the right". The blue part of the scale is visible. In case of "flow on the left" pull
off the rotary handle from the actuator. The scale must be pulled off from the housing, turned
by 180° and stuck on again. The red scale must be visible now (see "6 Change of the flow line ",
penultimate page of these instructions).
