Double diaphragm Spring brake actuator

Double diaphragm spring brake actuator (DDSB) consists of service brake chamber and a spring brake chamber. The air pressure applied into the service chamber is converted into mechanical output force. The spring chamber provides the mechanical braking force to park the vehicle. In addition, a mechanical release arrangement is provided in the unit to release the parking brake after brake failure. ProVia offers a cost attractive, high performance spring brake actuators for commercial vehicles.
