Units operating outside these conditions cannot be guaranteed to operate as
Type 2 valves.

The approved designations for Type 2 valves are as follows:
The permitted application details are:
†
Mixed water temperature at discharge point.
In order to achieve the safe water temperatures expected of a Type 2 valve, it is
essential that the unit is used only for the applications covered by its approved
designations, with the appropriate water supply pressures and temperatures. It must
be commissioned, maintained and serviced in accordance with the recommendations
contained in this guide. Refer to section “Maintenance, In-Service Tests” for
the in-service test frequency that must be used as a minimum guide in Type 2
installations.
Supply Conditions
For applications where a Type 2 valve is required, the supply conditions must comply
with the values in the table below. Note that both hot and cold supply pressures must
lie within the same pressure range.
