The OV valve insert DN 15-25 for the ADV 9 series is a highly developed product designed for the efficient control of heating and cooling systems. This valve insert offers a dual function, ensuring that in the event of disassembly or destruction of the thermostat, such as through vandalism, the valve automatically closes. This occurs down to a residual flow of 5% of the nominal capacity, ensuring reliable functionality. The insert is equipped with an external seal that allows for effective sealing and supports the longevity of the product. The dimensions of the thermostatic control element are M30 x 1.5, facilitating easy integration into existing systems. Thus, the OV valve insert is a practical solution for those who value safety and efficiency in their heating and cooling systems.

• Automatic closing of the valve in case of thermostat disassembly or destruction
