Valves and Plumbing Control Valves Solar Non-Return Valves

Solar Non-Return Valves

The RMC Solar Non-Return Valve is a high temperature non-return suitable for use on solar water heater systems.

Solar Non-Return valves prevent the backflow of heated water from a water heater to the mains line. This serves the dual purpose of protecting the mains supply from contamination and prevents the loss of water that has already been heated.

Solar and uncontrolled heating systems present an increased hazard to downstream components as water can become superheated and potentially flash to steam. Only high temperature non-return valves such as the Solar Non-Return Valve should be used in these circumstances.
