speciﬁ ed on the identiﬁ cation plate of the valve.

2. Description of the part, its item No. or spare

parts set number, and the quantity required.

9. Maintenance

If the ball segment or seat ring has sustained damage due

to impurities in the pipework or for some other reason, or

if the seat ring and stem seals need replacing after a long

period of service, the valve must be overhauled.

Many valves are installed in such locations that their

performance is of

decisive importance

to the entire

process. Such valves should be

inspected regularly and

any faults should immediately be corrected

9.1 To remove the valve from the pipework

The procedure for inspection and maintenance, for

which no special tools are necessary, is as follows:

1. Ensure that the recommended spare parts and

also the gaskets - important - for the pipe

ﬂ anges are available.

2. Close the valve.

3. Shut off all compressed air connections

and isolate all electrical connections to the

actuator.

4. Disconnect all compressed air lines and electric

cables connected to the actuator.

5. Release the ﬂ anged joint between the valve

and the pipework. Then lift out the valve. Don’t

use the actuator for lifting.

Apply all lifting

forces to the valve itself and not to the actuator

- see ﬁ g. 1.

Note the direction of ﬂ ow

which is shown by an

arrow on the valve body.

9.2 To inspect the ball sector and seat ring

1. If an actuator is ﬁ tted to the valve, remove it. See

section 9.3, items 1 and 2.

2. Remove the indicating pin (23 - ﬁ g. 4).

3. Turn the ball sector through more than 90°, until

it is no longer in contact with the seat ring.

4. Push the seat ring out of its seat at the valve

body inlet. Withdraw it past the ball sector -

between the ball sector and the inside

of the valve body - towards the outlet, and

remove it from the body.

* Three rings are requested per valve for DN 25 - 100, four rings per valve for DN 150 - 300
