Maintenance

INOXPA S.A.U.

10.250.30.02EN · (0) 2019/09

Proceed with caution. Personal injury can occur.

Never directly disassembly the clamps from the valve reading the instructions carefully.

Valve/actuator assembly and disassembly should only be done by qualified persons.

8.6. DISASSEMBLY AND ASSEMBLY OF THE ACTUATOR

Do not apply compressed air until the disassembly/assembly process is completed. The figure is a schematic
representation of some of the steps in the actuator disassembly process.

8.6.1. Disassembly

1. Remove the air fittings (18).
2. Locate the actuator in the base of the clamp or in the lathe

collet. A thick tube (102) and a shim (101) must be used
on the free end of the actuator.

3. Apply force to the shim. Once the cover (12) has dropped

15-20mm, remove the snap ring (45); this should have
sufficient free space to be able to remove it.

4. Reduce the force on the shim slowly until the top cover is

free (you will note that the spring no longer exerts
pressure).

5. Remove the cover (12), the piston (30A) and the sleeve

(35).

6. Extract the seals (20C & 20F), the scraper (60C) and the

bushing (11D) from the cover (12).

7. Remove the seals (20C & 20F) from the piston (30A).
8. Extract the bushing (11C) and the seal (20E) from the

shaft sleeve (35).

9. Extract the spring base (43B) and spring (06A).
10. Extract the spring assembly (06) without disassembling it.

Do not take the spring assembly (06) apart, as it contains a spring with an applied charge.

Valve and/or actuator assembly and disassembly should only be performed by qualified personnel.

8.6.2. Assembly

1. Fit the scraper (60), seal (20) and bushing (11B) on the

actuator body (01).

2. Fit the seal (20B) on the spring assembly (06).
3. Fit the seal (20E) and bushing (11C) on the shaft sleeve

(35).

4. Fit the seals (20C & 20F) on the piston (30A).
5. Fit the seals (20C & 20F), scraper (60C) and bushing

(11D) on the cover (12).

6. Insert the spring assembly (06) into the actuator body

(01).

7. Insert spring (06A), spring base (43B), shaft sleeve (35)

and piston (30A) into the cylinder (01).

8. Mount the top cover (12) on the cylinder.
9. Apply force to the shim so it lowers 15-20mm. Insert the

snap ring (45).

10. Reduce the force applied slowly until the tool no longer

touches the cover.

11. Install the air fitting (18 and 18A).
12. Apply compressed air to check the proper operation of the

actuator.
