4.1 Precautions
WARNING:
•
All procedures must be performed by qualified personnel.
•
When the process fluid is hazardous, thermal (hot or cold), or corrosive, take extra pre-
cautions. Employ the appropriate safety devices and be prepared to control a process
media leak.
•
Always wear protective clothing and equipment to safeguard the eyes, face, hands, skin,
and lungs from the fluid in the line.

CAUTION:
•
Disconnect electrical, pneumatic, and hydraulic power before servicing actuator or auto-
mation components.
4.2 Install the valve and topworks

The series 3, 5, 8, or 16 stainless steel bonnet Advantage 2.1 actuator can have the air inlets posi-
tioned in any quadrant.
•
The maximum valve operating pressure is 10.34 bar | 150 psig. This pressure is applicable up to
38ºC | 100ºF. Valves at maximum pressure cannot be used at maximum temperatures.
•
The maximum actuator pressure is 6.2 bar | 90 psi.
