Function, Specifications, Materials, and Key Parameters of DZ95259360105 Relay Valve Assembly

1. Function

The DZ95259360105 relay valve is a critical component in the vehicle's air brake system, primarily functioning as a control valve to accelerate the charging and discharging process. By shortening the (chōng qì, charging) and (pái qì, discharging) times, it enhances the brake response speed. Typically installed at the end of long pipelines (e.g., in trailer or semi-trailer brake systems), it directly connects the air reservoir to the brake chamber, enabling rapid air intake and thus improving braking efficiency.
