TABLE 4. Dimensions in Inches (Millimeters).
NOTE: Allow 3 inches clearance above actuator for removal. Mount MA/MF/MP/MPR-5XXX actuators above the valve body at 45° from vertical
on steam applications.
TABLE 5. Restrictions on Maximum Ambient Temperature for Valve Actuators.
CAUTION: Condensation can facilitate corrosion. Piping insulation must not cover any part of the actuator or mounting nut. With
40°F (4°C) water, the maximum allowable dew point temperature without a linkage extension is 68°F (20°C).
