• This can be done with the TVS 6000UD remaining in the steam line.
• Be sure to isolate the TVS 6000UD trap valve station both up and downstream by using separate shut-off valves before
performing any maintenance
• Open isolation valves (A-A') and (G-G')
• Open bleed valve (B&H) to atmosphere
• Open the blowdown/depressurizing (D) to atmosphere
• Loosen and remove the bonnet bolts and pull the bonnet assembly out of the valve body
• Remove the valve sealing rings, valve washers and lantern bushings using Armstrong extracting tool. Check to see if all
components have been removed. Inspect and clean any debris that might have remained in the valve body
CAUTION!
– ensure all components (TVS and trap) are cold before handling.
Installing New Isolation Valve Assembly
• Place Armstrong spare part # D125139 isolation valve assembly in the valve body
• Lightly tap the isolation valve assembly to the bottom of the valve body
• Coat the threads of the bonnet bolts with "Never Seize", insert bolts through bonnet holes and tighten evenly until the bonnet seats
on the valve body
• Check the TVS 6000UD isolation valve for proper operation by opening and closing the valve one or two times
• Open shut-off valves up and downstream from the trap valve station with its isolation valve in the closed position and check for
leaks with trap installed
• Follow the opening and closing sequences as explained on page 5
