Maintenance Tighten the bonnet fasteners in a crisscross pattern. For more information, see Fastener torque table for valve body to topworks in this manual. Make multiple crisscross passes to build up torque to the final table value. Make additional crisscross passes using final table values to evenly tighten each fastener to within 5% of torque value.
Maintenance If the actuator mode of Then ... operation is ... Fail close Load the air port in the bottom cover of the actuator with sufficient air to partially open the valve. Remove the bonnet fasteners. Lift the topworks assembly from the valve body. If the actuator mode of operation is fail open, then remove pressure load from the actuator.

Maintenance d) Continue rotating the PTFE diaphragm clockwise into the compressor while securing the backing cushion from rotating. Rotate the diaphragm until hard stop or heavy resistance is achieved and additional force does not significantly rotate the diaphragm into the compressor. If replacing a PTFE diaphragm, re-invert the diaphragm.

Maintenance Back off (no more than half turn) until the bolt holes in diaphragm and the bonnet flange align. 10. If the actuator mode of operation is fail open or fail close, select one of these steps. If the actuator Then ...
If leakage is present, then replace the spindle o-rings. Lubrication requirements WARNING: Standard lubricants are as outlined below. Special lubricants may be required for oxygen or other unique services. Contact ITT for evaluation of non-standard lubricants. ® Advantage Actuator 2.0 Maintenance Manual...
If present, remove the switch package. Disconnect the air lines. ITT recommends that the following steps be performed on a bench with the body removed from the actuator: a) Disassemble the valve. For more information, see Disassemble the valve in this manual.
One fixture exists for the series 3, 5, and 8 actuators and one for the series 16 actuator. If present, remove the switch package. Disconnect the air lines. ITT recommends that the following steps be performed on a bench, with the body removed from the actuator: a) Disassemble the valve.
Replace the actuator diaphragm for double acting actuator If present, remove the switch package Disconnect the air lines. ITT recommends that the following steps be performed on a bench with the body removed from the actuator: a) Disassemble the valve.
