7. MAINTENANCE
The ACTUATECH S.p.A. actuator, when installed and used properly, does not require maintenance, under normal use, as it's provi-
ded with sufficient lubrication for standard duration.
Send the actuator directly to ACTUATECH S.p.A. for inspection or extraordinary maintenance.
If the cap or piston seals need to be replaced, ACTUATECH S.p.A. can supply a kit containing spare parts.
WARNING: The seals must be replaced by qualified personnel and with the appropriate tools. ACTUATECH S.p.A. declines all re-
sponsibility for products that are repaired by third parties.
REPLACING THE SEALS
Disassembly.
Actuator disassembly operation must do with the actuator free from any pneumatic and electric connection and dismounted from the
valve.
Verify that the actuator is air bag free.
Check that the air port 2 and 4 are absolutely vented.
Use proper tools only.
A) Loosen the end cap screws (part N° 16) in cross sequence to remove the end caps (part n° 3). The end caps contain a seal
(part N° 8) on its seat that should be checked before replacement.
B) Hold the actuator in the vice and rotate the drive shaft until the pistons (part N°2) are released form the scotch-yoke groves (part
N° 4), then slip off the pistons from the cylinder (part N° 1). Do not use compressed air to remove the pistons from the body, this
operation could cause personal injuries.
