Regulus DBV2 ¾ "Double thermal drain protection-2-way valve
Regulus double thermal discharge safety device DBV2 ¾“ – Reliable protection against overheating
The Regulus DBV2 ¾" double thermal safety valve is a specially designed solution for protecting central heating systems. This safety valve ensures efficient temperature regulation by automatically draining hot water and replacing it with fresh water in the event of overheating. With its robust brass housing and precisely controlled thermostatic elements, the safety valve is designed for continuous use.
How does the double thermal safety device work?
The innovative design of the Regulus DBV2 ¾" reliably protects the heating system from overheating. As soon as the temperature reaches a set limit of 97 °C ±2 °C, the drain valve opens and drains hot water from the heating source. At the same time, the fill valve ensures the supply of cold water, quickly cooling the system.
This process occurs automatically, controlled by two thermostatic elements inside the valve. These close as soon as the water temperature has been reduced to a safe level, thus ensuring a continuously regulated heat supply without interruptions.
For which application is the Regulus DBV2 ¾“ suitable?
The double thermal safety valve is ideal for central heating systems where there is a risk of overheating. Thanks to a maximum boiler output of up to 220 kW (when using both elements), the valve is suitable for both residential and industrial heating systems. Its versatility is ensured by the high maximum temperature of 110 °C and the pressure resistance on the water side of up to 6 bar.
In addition, the DBV2 ¾” offers an excellent solution to increase the safety and efficiency of heating systems, especially in areas with a high demand for temperature control.

Installation tips for maximum security
If the pressure in the supply network exceeds 6 bar, it is essential to install a pressure reducer at the cooling water inlet. This prevents system overload and increases the longevity of the heating system.
Furthermore, it is recommended to adjust the pressure of the reducing valve accordingly – ideally to twice the required heating pressure, but at least to 2 bar. This ensures the safe operation of both the heating system and the thermal discharge safety device.
Conclusion – safety and efficiency in one
The Regulus DBV2 ¾" double thermal discharge valve offers an optimal combination of safety, robustness, and functionality. It reliably protects your heating system from overheating and ensures consistent temperature control. With its sophisticated design and high-quality materials, this valve is the perfect choice for anyone looking for long-term, reliable solutions.
