To be sure you are installing appropriate parts into your valve,
determine the model number. The easiest way to do that is to
look at the date code (found on the bonnet of the valve). The
date code (not to be confused with the product or part number)
is a four-digit code. Its purpose is to record the model/version
number of the product itself and the date of manufacture. (See
circle "B" in the figure for location of date code.)
The bonnet also indicates the maximum setting. In the figure,
circle "A" shows the location of the temperature range: "115"
(a standard valve).
Checkstops are required with this valve to
prevent crossflow.
