JRGUMAT JRG3400 thermostatic mixing valve is a gunmetal-bodied thermostatic mixing valve designed to proportionally regulate mixed water temperature without the need for external energy. It provides stable outlet temperatures with high control accuracy for domestic hot water and central distribution systems.
The valve operates via an internal thermostatic element that continuously compares the mixed water temperature to the setpoint and modulates the valve slide to maintain the required delivery temperature. When installed in systems requiring energy optimisation, select models include a fourth inlet port (20–50 mm valve range) to accept recirculated water once system set temperature is achieved, helping reduce unnecessary reheating and improving overall system efficiency.
To ensure correct performance, the installation must provide balanced hydraulic conditions at the hot and cold inlets, with hot water supply at least 5 K above the desired mixed water temperature.
The JRGUMAT is widely used as a central mixing valve and system protection device in residential, healthcare, hospitality, and commercial applications, and is also suitable for installations using alternative heat sources such as solar, biomass, wood, or pellet systems.
Features:
- Three-way thermostatic mixing valve in gunmetal construction.
- Optional fourth inlet port (20–50 mm sizes) for recirculated water.
- Proportional temperature control without auxiliary energy.
- Maintains constant mixed water outlet temperature.
- High control accuracy and system stability.
- Scald protection and improved user safety.
- Energy-saving operation through recirculation management.
- Suitable for central and distributed hot water systems.
Applications - Suitable for residential buildings, healthcare facilities, aged care, hotels, barracks, sports facilities, and commercial or industrial hot water systems. Particularly suited to systems requiring recirculation efficiency and integration with renewable or alternative heating sources where temperature stability and energy reduction are priorities.
