Thermostatic safety group – protection and comfort in one

The ESBE VMB423 safety group is a compact solution designed for hot water tanks, providing comprehensive protection for the installation and user comfort. The set combines the functions of several components, creating a reliable system to protect against the effects of improper installation operation. The construction based on brass guarantees durability and corrosion resistance, and careful workmanship ensures long-term trouble-free operation.

Construction and application

The VMB423 group consists of a built-in check valve and connections for a safety valve and a vacuum relief valve (not included). The key element is the thermostatic mixing valve of the VTA320/VTA520 series, which precisely regulates the hot water temperature in the range of 35-60°C. This gives the user confidence that the water temperature is always optimal and safe. A siphon integrated with the design minimizes the risk of water hammer.

The set is characterized by a nominal diameter of DN 20, an external connection diameter of 22 mm and a connection length of 43 mm. The pressure class of the device is PN 10, and the housing is made of brass. The temperature adjustment range is between 35-60°C.
