There is information present on each lever valve ranging in importance from the part number and serial number to the color of the paint
and casting numbers. This information is important for identifying the valve, installing it correctly, and obtaining parts. An example
of the current factory serial number label used on 1-1/2 thru 3 inch 322L Lever Valves is shown here. The accompanying table
identifies the information present and where to find it on the lever valve. There may also be other casting numbers and foundry marks
present that do not provide useful information. Customer specific tagging may also present. The labels or plates used, and information
present, on Warren Controls other product lines or older valves may be different, contact the factory for details.
