The RMC 15mm 1/2" 850kPa Expansion Control Valve is fitted to water heater inlets to relieve expansion pressure as water heats. By releasing pressure at the inlet, it helps protect the system and avoids purging heated water unnecessarily.
An expansion control valve is installed on the cold water inlet of a storage water heater to manage the pressure increase that occurs during heating. This RMC valve relieves that pressure at 850kPa, helping reduce wasted hot water and supporting safe, efficient operation of the hot water system.
RMC 15mm 1/2" 850kPa Expansion Control Valve is designed for use at water heater inlets, providing essential expansion safeguards. It is engineered to release pressure at the inlet, which conserves energy by preventing the unnecessary purging of heated water. The valve helps manage the pressure increase that occurs as stored water is heated.
