2. INSTALLATION
2.1 Mounting - The Lin-E-Aire ® Valve Actuator is normally fur-
nished mounted on a valve body. Follow the valve body instruc-
tions when installing the control valve in the pipeline.
Clearance should be left above and below the control valve to
permit removal of actuator and valve plug. Removal clearance
dimensions are specified in the control valve instructions, as well
as installation instructions. The actuator will sometimes be
shipped alone for field mounting on a valve body. Mount actuator
as outlined in the control valve instructions.
2.2 Pneumatic Connections - Connect the input pressure to
the 1/4˝ female NPT port on the top of an air-to-lower actuator or
under the diaphragm casing on an air-to-raise actuator, Figure 3
or 4. Either pipe or tubing may be used for the air line. The input
pressure must not exceed the limits listed under the specifica-
tions.
When there is a long distance between the actuator and the con-
trol device which produces the input pressure, or when a large
actuator size is required, there may be excessive transmission lag
in the control signal. A W.E. Anderson Valve Positioner, Catalog
Number 100N or 165, can be used to reduce the lag. If a valve
positioner is included with the actuator, connections between the
positioner and actuator are made at the factory. Refer to the valve
positioner instructions for additional connection information.
