Issue
Replacement stuffing box/stem seal
Environment
100108230
100108220
V321
100108210
Cause
When leaking by the gland, a stuffing box replacement may sometimes help.
Resolution
The DN125 to DN150 of the V321 valve was changed around mid 2007 (the other sizes remained unchanged). With this change the valve stem changed from diameter 18mm to 12mm.
Unfortunately it was not thought to to update the data sheet in regards to the gland service kits – the gland service kit was updated by the factory for the new stem dia. but there was no advice as to servicing the old valve.
Fortunately the stuffing box from the V222 and V292 valves of DN125 to DN150 also fits the V321 valve, thus gland kit 100108210 should be the correct gland kit to use if you have the old valve (stem diameter of 18 mm).
If you have the new V321 model (stem diameter of 12 mm): Replacement/spare stuffing box for V321 DN65-DN100 is part no 100108220 and for DN125-150 it is part no 100108230.
The DN125 to DN150 of the V321 valve was changed around mid 2007, just before I started working for Schneider so I had to do some investigation here.
With this change the valve stem changed from dia. 18mm to dia.12mm
Unfortunately it was not thought to change the part numbers for the valve, nor to update the data sheet in regards to the gland service kits – the gland service kit was updated by the factory for the new stem dia. but there was no advice as to servicing the old valve.
Fortunately the gland kit from the V222 and V292 valves of DN125 to DN150 also fits the V321 valve. Thus gland kit 1 001 0821 0 should be the correct gland kit to use.
