Produce overview
MUD distribution valve is designed for railway air brake system which conforms to UIC standard. It is widely used in different brake systems.
Distribution valve is an important spare part to guarantee safety of railway vehicle. In the air brake system of railway vehicle, distribution valve controls charging & discharging of the main air reservoir according to the variation of pressure in the hose. The quality of the distribution valve determines whether a railway vehicle can run safely.
