Thermostatic safety group ESBE VMB423 35-60°C CPF15 DN15 1.0MPa 31502600

Thermostatic safety group for hot water tanks

The ESBE VMB423 safety group is a compact solution designed for mounting on hot water tanks. The set combines safety and regulating functions, ensuring optimal operating conditions for the central heating and domestic hot water systems. The construction based on a brass housing guarantees durability and corrosion resistance, and careful workmanship facilitates installation and servicing.

Construction and application

The VMB423 group consists of several key elements: a built-in check valve and connections for a safety valve and a vacuum relief valve (not included). The heart of the group is a thermostatic mixing valve from the VTA320/VTA520 series, which precisely regulates the water temperature in the range of 35-60°C. Thanks to this, regardless of changes in the supply temperature, the user has access to water at a comfortable and safe temperature.

The use of the ESBE VMB423 safety group minimizes the risk of damage to the installation caused by excessive pressure or temperature. The check valve prevents backflow of water, which is particularly important in installations with electric or gas heaters. The siphon built into the group reduces flow noise and eliminates any pulsations.

Key features and benefits

• Compact design: space saving and easy integration with existing installation.
• Brass housing: high corrosion resistance and long-term use.
• Thermostatic temperature control: comfort of use and protection against burns. The adjustment range of 35-60°C allows you to adjust the temperature to individual needs.
• Check valve: protection against backflow of water and damage to the heater.
• Connections for safety and vacuum relief valves: possibility of expanding the group with additional safety elements (valves available separately).
• Clamping ring: ensures a tight connection with the piping installation with a diameter of DN15 (1/2 inch).
• Pressure class PN 10: safe operation at a maximum pressure of 1.0 MPa (10 bar).
• Built-in siphon: reduction of flow noise.

The ESBE VMB423 safety group is characterized by a nominal diameter of DN 15, a pressure class of PN 10 and a maximum working pressure of 1.0 MPa. The temperature adjustment range is from 35 to 60°C, and the housing is made of brass. Connection to the installation is realized with a clamping ring.

The ESBE VMB423 safety group is a reliable solution for both professional installers and end users looking for comprehensive protection of the domestic hot water installation. Its solid construction and precise temperature control guarantee comfortable use for many years.
