Thermostatic mixing valve ESBE VTA572 10-30°C G1 1/4 25-4.8 31700400

Thermostatic Mixing Valve – Precise Temperature Control in Your System

This thermostatic mixing valve ESBE VTA572, with a G1 1/4" connection and adjustable range of 10-30°C, is a reliable solution for heating and cooling systems. It ensures optimal comfort and safety by preventing excessively high temperatures, especially in underfloor heating systems. The valve is manufactured from dezincification-resistant (DZR) brass, guaranteeing long-term durability and corrosion resistance.

Construction and Application

The VTA572 valve from the VTA370 and VTA570 series is designed for precise blending of hot and cold water to maintain a set outlet temperature. Its asymmetric flow design and anti-scald protection make it an ideal choice for a wide range of applications—from underfloor heating and radiator systems to cooling installations. The ability to set the temperature range (in this case, 10-30°C) allows the valve to be tailored to specific system requirements. A Kvs value of 4.8 ensures sufficient flow capacity for efficient system operation.

Key Features and Benefits
