VSI Series 1000-X Electric Actuator
Operation and Maintenance Manual

MOUNTING ON A VALVE
1. NOTE: Direct mounting the actuator removes the
bracket and coupling from the mounting process,
but the remainder of the process remains the
same.
2. Rotate valve to fully closed position. Ensure that
the valve rotates freely with no obstruction.
3. Using the proper bolts attach the bracket to the
valve – tighten only loosely.
4. Apply grease or anti-seize to the valve shaft and
place the coupling onto the valve stem.
5. Using the manual override handle or handwheel,
rotate the actuator to the fully closed position so
that the position indicator displays “SHUT”.
6. Apply grease or anti-seize to the coupling at the
actuator interface.
7. Place the actuator onto the bracket, aligning the
coupling drive and actuator.
8. Attach the bracket with proper bolts and tighten
all bolts. If bolt holes are not aligned, but within
Installation of Actuator to Valve
5° alignment, rotate actuator handwheel to move
actuator into alignment.
9. Drive the actuator using the manual crank or
handwheel and confirm hat the valve rotates
without obstruction. Ensure the valve is fully open
as the actuator rotates to the full open position
• If using your own bracket or one provided by third
party supplier, ensure that the materials provided
are manufactured professionally and meet the
requirements of Figure 3.
• The coupling valve and actuator drive ends must be
absolutely coaxial to prevent damage to actuator.
• Poor locating of bolt holes in the bracket may
cause improper indexing of the valve and actuator,
preventing the actuator from fully opening or
closing the valve.
• Only tighten bolts after the actuator, bracket, and
valve have been properly aligned.
Mounting Tips
The coaxiality between axes A and B shall not exceed 0.2mm.
