The heater pipe shut-off valve for Citroën 11CV and 15CV vehicles, manufactured until July 1952, is a crucial component of the heating system. This valve controls the airflow through the heater pipe, ensuring the vehicle's interior is comfortably heated. It is specifically designed for older Citroën models where proper temperature regulation is key to driving comfort. The valve is easy to install and fits perfectly on the original pipe diameters. Quickly and efficiently replace old or worn-out parts for optimal performance, especially during cold seasons when reliable heating is essential for comfortable driving.
