6. SERVICE / SPARE PART
We recommend that valves be directed to Neles service centers for
maintenance. The service centers are equipped to provide rapid turn-
around at a reasonable cost and offer warranty for reconditioning
based on condition of each valve.
NOTE: When sending goods to the service center for repair, do not
disassemble them. Clean the valve carefully and flush the valve
internals. Include the material safety datasheet(s) (MSDS) for all
media flowing through the valve. Valves sent to the service center
without MSDS datasheet(s) will not be accepted.
For further information on spare parts and service or assistance visit
our web-site at www.neles.com/products .
NOTE: When ordering spare parts, always include the following
information:
a. Valve type code as per technical bulletin and model
number from name plate,
b. If the valve is serialized - the serial number (stamped
on the valve body or name plate) or applicable
manufacturing order number,
c. Spare part set number as per Table 3 .
