Troubleshooting
If You Experience Erratic Control:
•
Regulator may be oversized. Oversizing causes
cycling, hunting, and reduces the rangeability of
the valve – make certain that your valve has been
correctly sized for your application conditions
•
Valve seat may be defective - replace stem and/or
body.
•
Valve plug may not be moving freely – inspect the
cylinder and spring housing.
Upstream Pressure Build-up or Inability to Maintain
Regulated Pressure.
•
Inspect for jamming between cylinder and spring
housing.
•
Diaphragm may have failed - replace if necessary.
•
Piping may be blocked or undersized.
•
Range spring may be set too high or may be broken
- inspect and reset or replace as necessary.
•
The valve may be undersized for required flow -
make certain that the valve has been sized correctly.
Ordering Spare Parts
Use only genuine Steriflow 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
to provide your Steriflow 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 information: 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.
