1�8 Actuator Storage

For applications where the actuator is not placed into immediate service, it is recommended that the actuator be cycled with regulated clean/dry pneumatic pressure at least once per month. Indoor storage, if available, is recommended for all actuators. Care should be taken to plug all open ports on actuator and controls to keep out foreign particles and moisture. Actuators should not be stored in an atmosphere that is harmful to resilient

seals. Contact factory for extended storage period.

1�9 Actuator Installation

1.9.1 Since there are many valve and actuator combinations, it is not practical to include detailed instructions for each type. Mountings are designed to be as simple as possible to keep the guess work out of the installation.

1.9.2 Actuators that are shipped from the factory with the travel stops adjusted for

approximately ninety degree rotation. Generally, it is necessary to make slight

travel stop adjustments once the actuator is installed onto the valve. Refer to the

valve manufacturer's recommendations for specic requirements. When the valve

has internal stops, the actuator should be adjusted at the same points.

Service Instructions

127073E Rev. C

NOTE:

The actual "stopping" should be done by the actuator. If the valve does not have internal stops, adjust the actuator to the full open position. Using this as a reference point, rotate

the valve closed and adjust to the valve manufacturer's specications for total rotation.

1.9.3 Good instrument practices are also recommended. Clean/dry regulated pneumatic pressure is essential for long service life and satisfactory operation. It should be noted that new pneumatic lines often have scale and other debris in them and these lines should be purged of all foreign material.

NOTE:

Scale and debris can damage control valves, solenoids, and seals.

1�10 Actuator Start-up

1.10.1 Prestart-up checks

1. Inspect to ensure the unit has been mounted onto valve properly. Gear

ange mounting bolts, stem key, set screw(s) are installed and secured.

2. No tubing damaged or accessories dislodged during the shipping or the installation.

3. Indicated position conrms valve position.

4. All switching valves in normal operating position as per SCHEMATIC / INSTRUCTIONS

3�7 Actuator Testing

Section 3: Actuator Reassembly

August 2015

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

CAUTION: DO NOT EXCEED MAXIMUM PRESSURE

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.

3.7.2 Cycle the actuator ve times at the nominal operating pressure (NOP) as listed on the actuator’s name tag or the customer's 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 ve times as this will

allow the seals to seek their proper service condition.

NOTE:

If excessive leakage across the piston remains, the actuator must be disassembled and the

cause of leakage must be determined and corrected.

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

3.7.4 Apply a commercial leak testing solution to the following areas:

3.7.4.1 Joint between inner end cap (3-10) and cylinder (3-70). This checks

cylinder to inner end cap O-ring seal.

3.7.4.2 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).

3.7.4.3 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).

3.7.4.4 Remove pressure from the pressure inlet port.

Actuator Reassembly

Section 3: Actuator Reassembly

August 2015

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

3.7.6 Shell Pressure Test – Optional pressure test could be performed on PED certied actuator by applying pressure to both sides of the piston simultaneously for a period of two (2) minutes. If any leakage occurs across a static seal, the unit must be disassembled and the cause of leakage determined and corrected.

WARNING: PED PRESSURE TESTING

The actuators main pressure bearing parts will be tested in controlled conditions in accordance with the requirement of PED by pressuring both sides of the piston to avoid damage and over torquing of the actuator components. If further future testing in the field is necessary, Emerson should be contacted for guidance.

dened by the nal installer to achieve the dened SIL level.

7.2.1.1 Procedure

7.2.1.1.1 Stroke the actuator/valve assembly two complete open/close cycles with complete closing of the valve.

7.2.1.1.2 Verify the open/close cycles functioned correctly (e.g. check locally, or automatically via Logic solver, the correct movement of the actuator/valve).

Upon successful completion of the above described Full Stroke Test procedure, the

“Test Coverage” can be considered 99%.

7.2.2 Partial Stroke Test (when requested) The “Partial Stroke Test” (“On-line”) can be performed to improve the PFD and to satisfy PFD partial stroke value is 15% of the stroke and the recommended test interval is about every one to three months.

7.2.2.1 Procedure

7.2.2.1.1 Operate the actuator/valve assembly for No° 1 open/close

Section 8: Removal and Decommissioning

8�1 Removal and Decommissioning

WARNING: FOLLOW PROPER PROCEDURE

Always follow safe work practices remove and disassemble G-Series actuator.

The below basic procedure should not supersede or replace any customer’s plant safety or work procedures. If a conict arises between this procedure and the customer's procedures, the differences should be resolved in writing between an authorized customer’s representative and an authorized Emerson/Bettis representative.

CAUTION: ISOLATE AND POWER OFF ACTUATOR

Make sure actuator is isolated before removing from valve. Turn OFF the power medium and

bleed off all pressure rst, including storage tank (if present). Next, bleed off pilot pressure,

disconnect: pneumatic pressure supply, pilot tubing and electrical wiring (if equipped).

Before starting the disassembly, a large area should be created around the actuator so to allow any kind of movement.

Separate the parts composing the actuator according to their nature (ex. metallic, and plastic materials, uids etc.) and send them to differentiated waste collection sites, as pro-

vided for by the laws and provisions in force.

8.1.1 Drain tanks and remove tubing from actuator. Remove accessories (if equipped) and controls from actuator.

8.1.2 Remove all equipment mounted on top of actuator (limit switches, end of stroke valve, and relevant pneumatic/electric connection, etc.)

8.1.3 Remove mounting bolts and actuator is ready to be removed from valve. For complete actuator tear down refer to Section 2 of the manual.
