Double diaphragm Spring brake actuator

Provia’s double diaphragm spring brake actuator is a low-cost, highperformance universal component designed for compatibility with a wide range of commercial vehicles across the truck, bus and off-road vehicle sectors. Air pressure applied into the service chamber is converted into a mechanical output force while the spring chamber provides the mechanical braking force to park the vehicle. A mechanical release arrangement within the unit can release the parking brake in the event of a brake failure.
