Troubleshooting
If You Experience Erratic Control:
Oversizing causes cycling and hunting, and reduc-
es the rangeability of the valve. Make certain that
your sizing is correct.
Steam traps downstream may require maintenance.
Safety valve may be defective and need repair.
There may be excessive foreign matter on the
seats, and seats should be removed and cleaned.
Valve stroke may need readjustment.
Valve disc may not be moving freely. Check disc
guide clearance and correct if needed.
If Valve Will Not Operate:
Diaphragm may be ruptured and require replace-
ment.
Adjusting spring may be broken and require re-
placement.
Spring may be set improperly and require resetting.
Ordering Spare Parts
Use only genuine Jordan Valve parts to keep your valve
in good working order. So that we can supply the parts,
which were designed for your valve, we must know ex-
actly which product you are using. The only guarantee to
getting the correct replacement parts is to provide your
Jordan Representative with the valve serial number. This
number is located on the valve identification tag. If the
serial number is not available, the parts needed for your
valve might be determined using the following informa-
tion: Model Number, Valve Body Size, Seat Material and
Cv Rating, Spring Range and Set Point, Trim Material, Part
Name - Number and Quantity.
NOTE: Any parts ordered without a valve serial number
that are found to be incorrect are subject to up to a mini-
mum 25% restock charge when returned.
