Troubleshooting
Leaks
Multi-Port Valve Leaks
1.
Isolate and bleed down the pressure, and attempt to tighten the leak point . If leak persists, continue with next step .
2.
Re-tape the fittings on the multi-port valve .
a.
Remove the entire holder from the process line .
b.
Remove the multi-port valve from the holder .
c.
Disassemble and remove all the old Teflon tape from the multi-port valve and then re-tape the fittings .
d.
Reassemble the multi-port valve using a small amount of anti-seize lubricant on each fitting . Do not over-tighten
the fittings as this can cause a leak point .
3.
If the leak persists at a particular point, close the isolation valve, relieve pressure with bleeder valve, and contact
your representative or factory customer service .
Seal Leaks
If the holder is leaking from the top of the holder body where the rod and body meet, the PTFE seal is damaged and
requires replacement . See “Changing a Rod and Replacing the Seal Set” section .
Connection Leaks
1.
If the holder leaks from any threaded portion, immediately isolate the holder from the line and remove process
pressure .
2.
Remove the holder from the isolation valve .
3.
Remove the threaded component and use a small pick or screwdriver to remove Teflon tape from the threads .
4.
After tape and debris are removed, wipe down the threads with a clean rag .
5.
Reapply Teflon tape and anti-seize lubricant to the threads .
Â
NOTE
This procedure can be used for all connection points on a holder, including the multi-port valve, probe shaft adapters,
bleeder valves, and any other connections that may be on the holder .
Bleeder Valve Leaks
If the holder leaks from the bleeder valve outlet or bleeder valve stem, the bleeder valve is damaged and should be
replaced . Contact the factory to order a replacement valve .
Locking Collet
Not locking shaft in place
If the locking collet fails to lock the rod/shaft in place with 35 ft-lb (47 .45 Nm) of torque applied to the collet locking
bolt, the locking collet is damaged and must be replaced . Please contact the factory to order a replacement .
Do not interchange collets between tool holders . Collets are specially machined for each tool holder individually and cannot
be interchanged . Collet repair must be performed by the factory .
