•
Erratic Control – oversizing can cause cycling or
hunting (recalculate the size required). Undersizing can
cause the control point to drop off under peak loads
(increase the trim size). Inlet pressure to the valve
maybe varying significantly and the controller may not
be following it. (adjust the controller). Control loop may
require equal percentage trim if high rangabilities are
being utilized. Steam traps may need reconditioning.
Safety relief valves may be leaking. Valve stroke may
be out of adjustment or there may be foreign matter in
the valve preventing full movement.
•
Insufficient Flow – check shutoff valves to be sure
they are fully open. Inlet pressure to valve may be
insufficient to provide the needed flow (check the inlet
pressure with a pressure gauge). Strainers should be
checked for clogging and blown down if needed. Steam
traps may need reconditioning. Dirt in the trim may
prevent the valve from passing its full capacity.
Diaphragm failure or insufficient air pressure to reverse
acting (air-to-open) actuators would prevent the valve
from properly stroking open. Incorrect actuator spring
adjustment in reverse acting actuators would prevent
the valve properly stroking open.
•
Overpressure (outlet) – dirt in the trim may prevent
valve from shutting off. Diaphragm failure, incorrect
actuator spring adjustment, or insufficient air pressure
to direct acting (air-to-close) actuators would prevent
the valve from properly stroking closed.

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 exactly which product
you are using. The only guarantee to getting the correct
replacement parts is 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 able to be determined with the following information:
·
Model Number
·
Valve Body Size
·
Seat Material and CV rating
·
Spring Range and Set Point
·
Trim Material
·
Part Name – Number and Quantity
(See parts list chart)
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.
