Solenoid valve is divided into normally closed and normally open two types, mainly used in vehicle braking system.
At present, the solenoid valve of Shaanxi automobile assembly is DZ97189716021 (normally closed) and DZ97189716022 (normally open).
The solenoid valve assembled in early stage is 81.52160.6115 (normally closed type) and DZ9100716009 (normally open type).
Due to the technical upgrade of the main switch of the power supply since November 2018, the material and quality of the solenoid valve has been optimized. The appearance is different from the previous appearance, but the function and assembly size remain the same. Therefore, when the old state solenoid valve fails, the new state solenoid valve of the same type can be directly replaced.
