Reliance High Pressure and Temperature Relief Valve with 1" Extension 15mm 700kPa - HTE501

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.
