Model: HTE709
Reliance High Pressure and Temperature Relief Valve with 3/4" 20mm 1000kPa with 2" Extension- HTE709
RMC's HT Series valves are for use on mains pressure water heaters. They are available in a range of pressure settings from 500 kPa to 1400 kPa, and in 15 mm and 20 mm nominal diameters. Also available are extended shank models and versions with a hot water take-off.
RMC’s Pressure and Temperature Relief (P & T Relief) Valves are safety controls which ensure that the temperature of the water in a pressurised unvented water heater cannot exceed 99° C in the event that the normal thermostatic controls fail. These valves may be used to guard against overtemperature and over-pressure hazards wherever water is stored in unvented containers. This is a requirement of Australian Standard AS 3500-4. RMC P & T Relief Valves are available in 15 mm and 20 mm confi gurations.

The Pressure and Temperature Relief (P & T Relief) Valve should be installed at the heater. System inlet pressure should be no higher than 80% of the set pressure of the P & T Relief Valve. Please ensure that the set pressure of the High Pressure Expansion Control Valve is suitable for use with the water heater it will be installed with. For more information refer to the RMC Valve Application Guide.
