Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.

CAUTION
To avoid parts damage, do not use an operating pressure that exceeds the Maximum Diaphragm Casing Pressure (table 1)
or produces a torque greater than the Maximum Allowable Valve Shaft Torque. Use pressure‐limiting or pressure‐relieving
devices to prevent the diaphragm casing pressure from exceeding its limit.
To avoid parts damage
, do not stroke the actuator while cover (key 33) is off.
Actuator Mounting
Use the following steps to connect a valve and an actuator. Key numbers are shown in figure 8.
WARNING
To avoid personal injury, perform the steps in the WARNING at the beginning of the Maintenance section to isolate the
control valve and actuator.
1. Unscrew cap screws and washers (keys 34 and 63), and remove the cover (key 33).
2. Refer to figure 3 for available mounting styles and positions. When mounting on a Vee‐Ball V150, V200 or V300
valve, check the valve manual to determine if it is Series B. The actuator is normally positioned vertically with the
valve in a horizontal pipeline (see figure 3).
