3. The control valve must be installed with the actuator vertical above the valve body for proper operation. Flow
through the valve must be in the direction indicated by the flow arrow (key 15, figure 18, 19, or 20) on the valve
body.
4. Use accepted piping and welding practices when installing the valve in the line. For welding end valve bodies,
completely disassemble the valve removing all trim parts before welding the valve body in the line. For flanged
valve bodies, use suitable gaskets between the valve body flanges and pipeline flanges.

CAUTION
Depending on valve body materials used, post‐weld heat treating might be needed. Post‐weld heat treatment can damage
internal elastomeric, plastic, and metal parts. Shrunk‐fit pieces and threaded connections might loosen.
If post‐weld heat treating is needed, remove all trim parts to avoid any damage to internal elastomeric, plastic, and metal
parts. Contact your Emerson sales office
5. Install a three‐valve bypass around the valve if continuous operation is required during maintenance.
6. If the actuator and valve body are shipped separately, refer to the actuator mounting procedure in the appropriate
actuator instruction manual.
7. If the valve was shipped without packing installed in the packing box, install the packing before putting the valve
into service. Refer to instructions given in the Packing Maintenance procedure.
Valves with ENVIRO‐SEAL live‐loaded packing or HIGH‐SEAL Heavy‐Duty live‐loaded packing will not require this initial
re‐adjustment. See the Fisher instruction manuals titled ENVIRO‐SEAL Packing System for Sliding‐Stem Valves
(D101642X012) or HIGH‐SEAL Live‐Loaded Packing System (D101453X012) (as appropriate) for packing instructions.
If you wish to convert your present packing arrangement to ENVIRO‐SEAL packing, refer to the retrofit kits listed in the
parts kit sub‐section near the end of this manual.
