Air direct-pressure pinch valve
Air operated pinch valves / AFP-2 air operated series
AFP-2 is a product commissioned by DURHOLDT of Germany to produce according to Chinese standards at the initial stage of formulating the unified design standards for Chinese trains.
The valve body is formed by machining plastic profiles. Compared with AFC-I, the processing cost is slightly higher, the service life is slightly lower, the closing pressure is slightly higher, and the outer diameter is slightly larger.
