Mount the Advantage actuator to the valve
1. Regulate air pressure
Options
Description
If the actuator mode of
operation is ...
then ...
1 or 3
regulate the air pressure in the upper cover to extend the
compressor.
2
regulate the air pressure in the lower cover to properly position
the valve diaphragm.
2. Follow steps in Install diaphragm.
3. Assemble the valve body following the steps in Tighten the bonnet fasteners.
4. Travel stop, if equipped, must be reset at this time to ensure proper closure. Follow steps in Adjust
the travel (closing) stop.
Tighten the bonnet fasteners
Caution: Do not tighten fasteners while the system is pressurized or at elevated
temperatures (> 100°F/ 38°C).
1. Depressurize the system.
2. Use regulated air pressure to position diaphragm so that valve is slightly open. It may be necessary to
use air pressure to actuate the valve.
3. Tighten the bonnet fasteners in a crisscross pattern in accordance with the Fastener torque table for
valve body to actuator.
4. Make multiple criss-cross passes to build up torque to the final table value. Make additional criss-cross
passes using final table values to evenly tighten each fastener to within 5% of torque value.
5. Retighten the bonnet fasteners as noted above at ambient conditions after the system has cycled
through operating pressure and temperature.
6. Monitor the valve for leakage.
If ...
then ...
leakage occurs at the body/bonnet
flange sealing area
depressurize the system and retighten the bonnet
fasteners as noted above.
leakage continues
follow the steps in Replace valve diaphragm.
