Information Present on 326L Lever Valves
There is a great deal of information present on each lever valve ranging in importance from the part number and serial
number to casting numbers. This information is important for identifying the valve, installing it correctly, and obtaining
parts.
Examples of the current factory serial number label used on bronze and stainless steel ½ thru 2 inch
326L Lever Valves and the flow diagram plate used on stainless steel ½ thru 2 inch 326L Lever Valves are
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.
