The actuator travel stops should be adjusted so that there
is proper ball position in the full open and full close valve
position. Use the following procedures to determine correct
ball position.
Valve Open Position: With the valve in the open position
(actuator is against the “OPEN” travel stop), The maximum
allowable misalignment of the ball port in relation to the
body port is 1/32 inch (0.8 mm) on either side of the ball. Do
not use the seat ID to measure misalignment since, in many
cases; it is larger than the ball or body port.
Valve Close Position: With the valve in the closed position
(actuator is against the “CLOSE” travel stop), make a
pencil mark on the ball at the 9:00 o’clock and 3:00 o’clock
locations as shown in (Figure 6). Open the valve part way,
and measure dimension “A”. This measurement should
deviate no more than ± 1/32 inch (± 0.8 mm) from the value
given in (Table 8) for all valves.

6. SERVICE / SPARE PART
We recommend that valves 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 valve warranty with all reconditioned valves.
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.metso.com/valves.
NOTE: When ordering spare parts, always include the
following information:
a. Valve catalog code from identification plate,
b. If the valve is serialized – the serial number (from
identification plate)
c. From Figure 8, the ballooned part number, part
name and quantity required.
