Low Pressure Expansion Control Valves limit the maximum pressure in a pressurised, unvented water heater system by relieving excess pressure to the drain line.
Low Pressure Expansion Control Valves should only be installed on the cold or inlet installation on a water heater as the valve is primarily intended to cope with the excess pressure generated during a normal heating cycle.
RMC Low Pressure Expansion Control Valves are available in 15 mm and 20 mm configurations.
