For valves according to ATEX, please refer to specific instructions before read the following.
ATTENTION! The following instruction must be done only by competent staff and with the cold valve.
Furthermore the system must not be in working condition and with pressure inside the valve.
1. Deliver air to the servocontrol (6 bar) to lift the plug from its seat.
2. Unscrew the ring nut (part. n.9) and remove the valve body (part. n.11).
3. Cut off air from the servocontrol.
4. Since the servocontrol contains a pre-tensioned spring (part. n.5), to avoid injury, unscrew the screw (part.
n.7) slowly and with the servocontrol mounted in a suitable vice, to progressively release spring tension.
5. At this point the cylinder (part. n.1) can be removed.
6. Unscrew the nuts (part. n.6/13) without ruin the surface of the shaft.
7. Extract the plunger (part. n.2) from the shaft, then extract the shaft from the intermediate body (part. n.4).
8. -"FP94-BP94" DN015-050 servocontrol Ø50 - Ø70 - Ø100 (MZ10200): unscrew the three nuts (part.n.8)
and remove the cylinder guide (part.n.3). at this point all parts in the intermediate body can be extracted in
order to replace all the gaskets.
