See also separate actuator and accessory instructions
for additional installation guidelines.
• Be sure that the flow medium, ambient temperature and the select-
ed 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 In-
formation Present on Control Valves section for location of important
information on valve).
• Follow good piping practices. Install a bypass around the valve. In-
stall stop valves in inlet and outlet piping to provide means to isolate
valve.
• A straight run of pipe is recommended for 10 pipe diameters up-
stream of the valve and 20 pipe diameters downstream of the valve.
• Protect valve and downstream equipment with a self-cleaning strain-
er.
• 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 check-
ing 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 sup-
ported independent of the valve. DO NOT MOUNT DL115 ACTUA-
TORS IN THE HORIZONTAL POSITION.
• Be sure to leave clearance to allow for actuator removal (See Dimen-
sions & Weights of Product Specification section 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 informa-
tion 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.
INSTALLATION
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.
