INSTALLATION
See also separate actuator and accessory
instructions for additional installation guidelines.
• Be sure that the flow medium, ambient temperature and the
selected location will not exceed the maximum temperature
of the valve, actuator, or accessories. 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 adjustment 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 independent of the valve. DO NOT MOUNT
DL115 ACTUATORS IN THE HORIZONTAL POSITION.
• 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).
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.
