Over the last few years, ProVia has built an extensive and popular range of Spring Brake Actuators. This range has recently been enlarged to include, for the first time, Double Diaphragm Spring Brake (DDSB) Actuators for disc brake applications.

For drum brakes, the existing range already features Spring Brake Actuator Cam (16 part numbers) and DDSB Actuator Cam (25 part numbers). Disc brake applications featured four part numbers for standard spring brake actuators systems. Now, four further part numbers add a DDSB Actuator for disc brakes to the portfolio.

The universal design of the DDSB disc unit has been created to be compatible with most popular trailer makes and models, including those from BPW, Gigant, Haldex, Knorr, Kögel, Krone, SAF, Schmitz and Valx. Two of the new part numbers feature the pipe extension required by some BPW and SAF trucks, allowing for a simple air pipe assembly process. They are designed to fit the most popular 16/24 & 20/24 disc applications.

ProVia, the budget aftermarket brand from WABCO, takes a zero-compromise approach to safety, with design, testing and manufacturing processes all rigidly held to the highest standards. The range of DDSB Actuators are certified by the TÜV standards agency, and all also meet the SAE standard.
