RMC Valve Product Groups

Pressure and Temperature Relief Valves: RMC's Pressure and Temperature Relief (P & T Relief) Valves are safety controls fitted to pressurised hot water systems. These valves ensure that the temperature of the water in a pressurised, unvented water heater cannot exceed 99°C in the event that the normal heater thermostat controls fail.
Expansion Control Valves: RMC's Expansion Control Valves are fitted to the inlet of a water heater and limit the maximum pressure in the system.
Pressure Control Valves: RMC's Pressure Control Valves reduce or limit supply pressure to a preset maximum pressure.
Isolating & Non-Return Isolating Valves: RMC Non-Return Valves prevent the backflow of water from a water heater to the mains line. Isolating valves are used to provide a shut-off on the supply line for ease of servicing.
Tempering Valves: RMC Tempering Valves are primarily intended for application at the water heater. They mix hot water from the heater with cold water to deliver tempered water at a constant temperature throughout an entire house, building or system.
Solar Control Valves: RMC Solar Control Valves are specifically intended for use with solar water heaters. The range includes a number of valves, performing the various functions of a non-return valve, line strainer, pressure limiting valve and other more specialised controls.
Other Valves & Products: RMC offer a range of other valves and controls, including flow regulators, test kits and vacuum relief valves.
