SERVICE / SPARE PARTS
We recommend that actuators be directed to our service
centers for maintenance. The service centers are equipped
to provide rapid turn-around at a reasonable cost and offer
new actuator warranty with all reconditioned actuators.
NOTE: When sending goods to the service center for repair,
do not disassemble them. Clean the actuator prior to
shipping.

tance visit our web-site at www.metso.com/valves.
NOTE: When ordering spare parts, always include the fol-
lowing information:
A. Actuator catalog code from label,
B. If the actuator is serialized – the serial number
(from identification plate)
C. From Figure 23, the ballooned part number, part
