Thermal balancing valves are designed for use in circulating hot water systems. The balancing valve works by regulating the flow of water within it depending on the temperature.
Once the water temperature rises to its set point at 70°C, the thermal balancing valve restricts the flow. A bypass opens following a higher flow rate for disinfection purposes to protect against Legionella.
The balancing valves provide thermal balance in hot water systems in order keep a constant temperature within the system and limiting the flow in circulation pipes to a minimum required level. With a dry-fit thermometer there’s no need to drain the system down and the tamper proof cap secures the settings in place.
