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.
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.
• 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.

All other positions reduce service life of equipment.
NEXT BEST POSITION
45º from vertical above piping on either side.
Valve must have an 8 Bolt Flange.
WORST POSITION (Horizontal on either side).
VERTICAL BELOW PIPING
Position is suitable for gases, but not for liquids or steam.
a non-vertical mounting position may be necessary
to protect actuator in high temperature applications,
but may reduce packing life.
OPTION B: L’s with U-BOLTS
