Valve Positioner Mounting Kits for Rotary Actuators
This Instruction describes the use of a Siemens valve positioner mounting kit to mount a Siemens SiPART® PS2 or
ValvePAC™ Series 760 valve positioner on a typical rotary valve actuator.
positioner and for the actuator should be available for reference. If assistance is needed, refer to the
Customer/Product Support section of this instruction.
Figure 1 shows typical mechanical feedback configurations. The PS2 and Model 760 mount similarly and they use
similar feedback components.
KIT CONTENTS AND VARIATIONS
Each mounting kit contains:
•
A main bracket for the particular positioner-to-actuator mounting requirements
•
Hardware to mount the bracket to the valve positioner
•
Hardware to mount the bracket to the valve actuator – When bracket-to-actuator mounting hardware is not
supplied, actuator hardware that aligns with the main bracket mounting holes is removed from the actuator and
used to secure the main bracket.
•
Additional hardware (e.g. spacers) as required – An installation may
require use of spacers, supplied in some kits, between the positioner
mounting bracket and the actuator.
•
Feedback components to transfer the rotary motion of the actuator to the
valve positioner input shaft (may be sold separately)
•
When using a sheet metal coupler (see the detail at right), ensure that
the PS2 feedback arm attaches securely to a C-style metal coupling by
positioning the included metal spacer between the coupling and the
lockwasher.
KIT INSTALLATION
Before proceeding, read the actuator and valve positioner installation instructions and note all warnings and
cautions. Also, read the following cautions as they apply to all procedures in this instruction.
CAUTION
Perform the following steps to mount the positioner on the actuator and complete the feedback connection. Some
steps are performed only for certain models or certain actuator configurations as indicated.

KIT INSTALLATION INSTRUCTION
SiPART PS2 and ValvePAC Series 760
Do not apply supply pressure to the actuator or the valve positioner
during the installation process. Applying supply pressure before the
equipment is properly mounted could cause unexpected movement that
could lead to personal injury or equipment damage.
