It may be a requirement that the hot and cold water supply pressures to a Temperature Limiting Device (TLD)
are equal. If this is the case, a Pressure Limiting Valve (PLV) with the same pressure rating as the PLV for
the hot water is required for the TLD as shown.
NOTE
Valves with pressure ratings other than specified are unsuitable & must not be used.
