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
minimum 25% restock charge when returned.
Reversing Valve Action
To reverse the action of the control valve, rotate the disc
and plate 180°. A slight stroke adjustment is necessary
as outlined on the previous page, depending on the
valve action now required.
