Regulus double thermal drain safety device DBV2 ¾" – Reliable protection against overheating
The Regulus double thermal drain safety device DBV2 ¾" is a specially developed 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 drain safety device is designed for permanent use.
How does the double thermal drain 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 discharges hot water from the heat source. At the same time, the fill valve supplies 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 lowered to a safe level, ensuring a continuously regulated heat supply without interruptions.
For which applications is the Regulus DBV2 ¾" suitable?
The double thermal drain safety device is ideal for central heating systems where there is a risk of overheating. Thanks to the maximum boiler output of up to 220 kW (when using both elements), the valve is suitable for both private and industrial heating systems. Its versatility is ensured by the high maximum temperature of 110 °C and pressure resistance on the water side of up to 6 bar.
Furthermore, the DBV2 ¾" offers an excellent solution for increasing the safety and efficiency of heating systems, especially in areas with a high demand for temperature control.

Installation tips for maximum safety
If the pressure in the supply network exceeds 6 bar, it is essential to additionally install a pressure reducer at the inlet of the cooling water. This prevents overloading of the system and increases the longevity of the heating system.
Furthermore, it is advisable to adjust the pressure of the pressure reducing valve accordingly – ideally to twice the required heating pressure, but at least 2 bar. This ensures safe operation of both the heating system and the thermal drain safety device.
