RMC’s Pressure and Temperature (P&T) Relief Valves are safety controls for unvented water heaters. They ensure that the pressure and temperature of the water do not exceed 99°C in the event the normal thermostatic controls fail.
These valves may be used to guard against over-heating and overpressure hazards wherever water is stored in unvented containers. This is a requirement of Australian Standard AS/NZS 3500-4.
RMC P&T Relief Valves are available in 15mm and 20mm configurations.
