## Long description

Herz four-way mixing valve VUA-50 is designed for towel radiators and ladder-type heated radiators to provide stable outlet temperature and improve system efficiency. The valve mixes flow and return water to regulate the radiator heat output, allowing the installation to maintain set conditions even with variable system load. Intended for integration into bathroom towel warmers, the valve supports precise temperature control while minimizing thermal shocks and energy waste.
Advantages
The VUA-50 four-way valve offers reliable hydraulic mixing with durable construction suitable for domestic and light-commercial bathroom installations. Its design ensures consistent radiator temperature by blending supply and return flows, which reduces overheating and cycling of the heating source. The valve supports stable operation under varying flow rates and helps to optimize the overall heating circuit efficiency.
Suitable for
 Towel radiators and heated ladder-style radiators in bathrooms
 Retrofit installations where outlet temperature stabilization is required
 Systems that require hydraulic mixing to protect low-temperature heat sources
Key specifications
 Function: four-way hydraulic mixing valve for radiator temperature control
 Application: towel radiators and ladder-type heated radiators
 Temperature control: mixes supply and return to stabilize outlet temperature
 Installation location: inline with radiator connections in a heating circuit
 Materials and corrosion resistance: manufactured for heating system environments (metal alloy components and seals)
How to use
Install the four-way mixing valve in the radiator return or connection area according to the radiator manufacturer’s layout and standard plumbing practice. Adjust the valve setting or actuate with a compatible actuator where applicable to achieve the required outlet temperature. Commission the installation by balancing the heating circuit, checking flow direction, and verifying stable outlet temperature during different load conditions.
