Ball Valve Installation Tips
|
Always follow standard safety procedures when working on a valve. Flush the pipeline before installing the valve. Debris allowed to remain in the pipeline (such as weld spatters, welding rods, bricks, tools, etc.) can damage the valve. After installation, cycle the valve a minimum of three times and re-torque bolts as required. FOR BUTT WELD END VALVES Ensure that the valve is in the open position and the inside of the body bore of the valve body/body end is coated with a suitable spatter guard. The post weld heat treatment must be localized. Make sure to keep intense heat away from the main portion of the valve (seats and ball). Do not cover valve in stress relieving blankets. The temperature of the main body section should not exceed the rated valve temperature. In certain applications, it may be necessary to remove all internal "soft" material because of contractor heat treatment requests.
