SCOTCH–YOKE PART TURN PNEUMATIC ACTUATOR

GD2880 - GD8000 AND GS1440 - GS4000

7. MAINTENANCE

The ACTUATECH S.p.A actuator, when installed and used properly, does not require maintenance, under normal use, as it's provided

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, and the spring return actuator is completely in its springs rest position.

Check that the air port 2 and 4 are absolutely vented.

Use proper tools only.

A) Loosen the end cap screws (part N° 20) in cross sequence to remove the end caps (part n° 3), in case of force on the screws that

means that the actuator is still under air or spring action and the operation should be discontinued until the action is removed. The

end caps contain a sealing O-ring (part N° 19) on its seat that should be checked before replacement.

Caution. The Spring Return end caps cartridges (Parts N° 3 + 18+24+19+23+22+21) are a safety device, where the preloaded spring

is set to avoid the dangerous spring jumping. Do not release the screw (part N° 21) to remove the spring from its seat, this operation

must be done by ACTUATECH technician only.

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° 5), 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.
