Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
To avoid personal injury or property damage resulting from the sudden release of pressure, do not install the valve
assembly where service conditions could exceed the limits given on the valve and actuator nameplates. Use
pressure-relieving devices as required by accepted industry, local, state, or federal codes, and good engineering practices.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
WARNING
Avoid personal injury or property damage caused by uncontrolled movement or dropping of the valve assembly.
Hoist rings are sized to lift only the valve and actuator. Do not use hoist rings to lift the valve if piping or other structures
are added.
Rig the lift to use two hoist rings and take appropriate precautions to avoid unbalanced loading which may result in sudden
swinging or movement of the assembled unit, including additional lifting and/or support methods when necessary.
Failure to utilize safe lifting practices may result in equipment damage and/or personal injury.

2. Install a three-valve bypass around the control valve assembly if continuous operation will be necessary during
inspection and maintenance of the valve.
3. Inspect the valve body for damage and be c ertain that the valve body cavity is free of foreign material.
4. Be certain that adjacent pipelines are free of any foreign material, such as pipe scale or welding slag, that could
damage the valve body seating surfaces.
5. A V250 valve is normally shipped as part of a control valve assembly, with a power or manual handwheel actuator
mounted on the valve. If the valve and actuator have been purchased separately or if the actuator has been
