INSTALLATION
When Installing This Product…
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous
condition.
2. Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
IMPORTANT
1. Do not lift the valve by holding the stem.
2. Do not mount the valve with the stem pointed lower
than horizontal.
3. Mount the valve with the flow arrow pointed in the
direction of flow through the valve.
4. Mount the valve between aligned pipes. Mounting
the valve on pipes that are not aligned causes
leakage at the valve-to-pipe connection.
5. Ensure complete engagement on pipe to valve body
threads.
6. Hold the valve body with a clamp or pipe wrench on
the hexagonal fitting nearest the pipe to prevent
damage to the valve body while mounting on the
pipe. Refer to Fig. 4.
7. Be sure to allow enough room for installation and
service. Clearance for valve installation is dependent
on actuator size and the valve pipe size.
Location
Select a location where the valve, linkage, and actuator are
within the appropriate pressure and temperature ratings.
Leave sufficient clearance above the valve to accommodate
actuator installation and allow room for servicing the valve
body. (Completely install the valve body in the pipe line before
installing the actuator and linkage.)
When selecting a location for the valve, consider actuator
mounting restrictions. Modutrol IV™ Motor crankshafts must
be mounted horizontally.
