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 (see Catalog 14). 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 for
Type 1051 actuators and in figure 9 for Type 1052
actuators.
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 Design
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).
