This valve adjustment key is designed for setting valves on Citroën engines of the 11CV and 15CV type. The tool supports accurate positioning of valves and pushrods during maintenance and overhaul. Its flat, elongated shape with a size of 70 by 200 millimetres allows access to narrow engine compartments. The material is suitable for repeated use in a workshop environment. The key fits common valve mechanisms of these models and enables consistent adjustment quality during regular valve setting work and checking of valve clearance. It serves as a practical aid for mechanical servicing of classic Citroën valve trains.
