In order to cooperate with the formulation of unified design standards for trains in China, AFP China Railway Pinch Valve is an innovative product specially developed with independent intellectual property rights. Compared with German products, the whole injection moulding and embedding technology is adopted in the structure to eliminate the potential leakage between the original assemblies, and at the same time to reach the 1 million measured switch times twice the nominal life of German products.

As an original manufacturer's spare parts, it has equipped about 1000 carriages of Chinese trains.

It is interchangeable with the iron-European type pinch valve in AFP.
