See also separate actuator and accessory instructions for addi-
tional installation guidelines.
• Be sure that the flow medium, ambient temperature and the selected loca-
tion will not exceed the maximum temperature of the valve, actuator, or ac-
cessories. Information can be found in the product specifications and on the
nameplate(s) regarding these limits (See Information Present on Control Valves
section for location of important information on valve).
• Follow good piping practices. Install a bypass around the valve. Install stop
valves in inlet and outlet piping to provide means to isolate valve.
• A straight run of pipe is recommended for 10 pipe diameters upstream of the
valve and 20 pipe diameters downstream of the valve.
• Protect valve and downstream equipment with a self-cleaning strainer.
• Provide proper inlet and outlet drainage in steam service to prevent water
hammer or possible erosion in equipment.
• Install gauges in inlet and outlet piping to provide means for checking adjust-
ment and operation.
• For maximum efficiency and minimum wear install valve in vertical position
with the stem pointing upward.
• Actuators mounted in any position other than vertical must be supported inde-
pendent of the valve.
• Be sure to leave clearance to allow for actuator removal (See Dimensions &
Weights section of Product Specification for actuator removal clearance).
• Before installing, be sure valve and piping are clean inside and free of scale,
chips, welding spatter, and foreign material. Thoroughly blow out or flush pipe
lines.
• The valve must be installed with the fluid flowing in the correct direction(s). For
proper operation in all applications, control valves must be piped according to
the corresponding flow arrows, inlet markings, and port markings present on
each valve (See Information Present on Control Valves section for location of
important information on valve).
• Pipes must be aligned squarely with the valve at each connection.
• If the valve has screwed ends, do not apply pipe dope to the threads of the
valve body or to the first two threads of the pipe.
• If the valve has flanged ends, tighten flange bolts evenly to prevent excessive
stress and the possibility of cracking.
• If the valve has welded ends, prevent plug and cage distortion by keeping ex-
cess heat from the body.
!
Check valve for any
damage due to improper
storage or transportation.
Immediately notify your
sales organization of any
damaged goods upon
receipt. Do not attempt to
move or disturb the valve
further so photos may
be taken. If the shipping
container is noticeably
damaged refuse receipt,
as the shipping company
should be held liable until
a shipping representative
is available to take photos.
