3.9

3.8.3

Install ES stop screw (5-50) through ES blind end cap (5-10).

ACTUATOR TESTING

3.9.1

Leakage Test - All areas where leakage to atmosphere may occur are to be checked, using a commercial leak testing solution.

CAUTION: Pressure applied to the actuator is not to exceed the maximum operating pressure rating listed on the actuator name tag. Test the actuator using a properly adjusted self relieving regulator, with gauge.

3.9.2

Cycle the actuator five time at the nominal operating pressure (NOP) as listed on the actuator name tag or the customers normal actuator supply pressure. If excessive leakage across the pistons is noted, generally a bubble which breaks three seconds or less after starting to form, cycle the actuator five times as this will allow the seals to seek their proper service condition.

3.9.3

Apply NOP pressure to the pressure port in inner end cap (3-10) and allow the actuator to stabilize.

3.9.4

Apply a commercial leak testing solution to the following areas:

3.9.4.1 Joint between inner end cap (3-10) and cylinder (3-70). This checks cylinder to inner end cap o-ring seal.

3.9.4.2 The port hole in the outer end cap (3-80). This checks the piston D-seal to cylinder (3-70), o-ring seal (4-70), and rod T seal (4-50).

NOTE: If excessive leakage across the piston remains, the actuator must be disassembled and the cause of leakage must be determined and corrected.

3.9.4.3 The vent check port hole in housing. This checks Polypak seal (4-30) that seals piston rod (3-40) to inner end cap (3-10).

3.9.4.4 Remove pressure from the pressure inlet port.

3.9.5

If an actuator was disassembled and repaired, the above leakage test must be performed again.

SPRING MODULE INSTALLATION

CAUTION: Due to the weight and size of Spring Module, heavy duty support equipment will be required when installing spring cartridge module to the actuator housing. For the approximate weight of the spring cartridge refer to Section

6.

WARNING ACTUATOR MUST BE IN THE APPROPRIATE OVERTRAVEL POSITION

(Refer to detail “A” on warning tag attached to Spring Module access hole cover or to Bettis drawing part number 130084 for G01 models or part number 123650 for G2 through G13 models). Confirm over-travel position by observing the guide block (1-30) is against the inner wall of housing (1-10).

NOTE: The setting of stop screws (1-180) should be checked and setting recorded before stop screws are loosened or removed.

5.2.1

On stop screw (1-180), that is located on the same side of the housing as spring cartridge

(5-10), loosen stop screw nut (1-190).

5.2.2

Unscrew or back out stop screw (1-180) to achieve over-travel as illustrated in detail “A” on warning tag attached to Spring Module cover plate or to Bettis drawing part number

123650.

5.2.3

Install o-ring seal (6-20) into the o-ring groove in the inboard end of spring cartridge assembly (5-10).
