2 Unpacking
2.1 While unpacking the valve, check the packing list against the materials received. Lists
describing the valve and accessories are included in each shipping container.
2.2 When lifting the valve from shipping container, use straps through the yoke legs, or the lifting
lugs attached to the yoke bolting. Take care to position lifting straps to avoid damage to the
tubing and mounted accessories.
WARNING: When lifting a valve be aware that the center of gravity may be above the lifting point.
Therefore, support must be given to prevent the valve from rotating. Failure to do so can cause
serious injury to personnel and damage to the valve and nearby equipment.
2.3 Contact your shipper immediately if there is shipping damage.
2.4 Should any problem arise, call your Flowserve representative.
3 Installation
DANGER: Before installation check the order number, serial number, and/or the tag number to
ensure that the valve and actuator being installed are correct for the intended application.
CAUTION: Do not insulate extensions that are provided for hot or cold services.
CAUTION: On valves equipped with air filters, the air filter must point down to perform properly.
NOTE: In some rare cases, the air supply must be limited to less than 150 psi (10.3 bar). This is
indicated on a sticker found near the upper air port on the actuator cylinder. An air regulator should
be installed to ensure the supply pressure does not exceed the line pressure indicated on the sticker.
3.1 Pipelines must be correctly aligned to ensure that the valve is not fitted under tension.
3.2 Fire protection must be provided by the user.
3.3 Before installing the valve, clean the line of dirt, welding chips, scale and other foreign
material.
3.4 Whenever possible, the valve should be installed in an upright position. Vertical installation
permits easier valve maintenance.
3.5 Be sure to provide proper overhead clearance for the actuator to allow for disassembly of
the plug from the valve body. Refer to the appropriate actuator User Instructions for proper
clearances. Actuator User Instructions are available at www.flowserve.com.
3.6 Double-check flow direction to be sure the valve is installed correctly. Flow direction is
indicated by the arrow attached to the body.
3.7 If welding the valve into the line, use extreme care to avoid excess heat buildup in the valve.
3.8 Connect the air supply and instrument signal lines. Throttling control valves are equipped with
a valve positioner. Refer to the appropriate positioner bulletin for connections, maximum air
supplies, and maintenance instructions.
