Part Number: 81521066067
Description:
This listing is for a genuine MAN EBS pressure valve / brake modulator assembly removed from a MAN TGS / TGX Euro 6 truck. The unit combines an electronic control module and pneumatic valve block to regulate brake pressure within the EBS (Electronic Braking System) on the front axle. OE part numbers include MAN 81521066067 / 81.52106-6067 and Knorr-Bremse K050211 / K050211N50, as confirmed by specialist MAN parts catalogues and commercial vehicle suppliers.
The valve is designed for 24V commercial vehicle electrical systems and interfaces with the chassis EBS wiring harness and air lines via multiple threaded ports. It is typically chassis-mounted near the front axle on MAN TGS and TGX Euro 6 tractors and rigids. Similar units are described by MAN and aftermarket catalogues as “EBS pressure valve” or “EBS pressure control valve”, and by various dealers as brake valve or EBS modulator for MAN TG-series trucks.
This particular item is a used original component. It was checked for correct functionality on the donor truck prior to dismantling with no active EBS errors. After removal the part was visually inspected, lightly cleaned externally and stored dry. There are visible signs of normal service such as oxidation on the metal air ports, dirt staining and minor cosmetic marks on the housing, but no apparent structural damage or broken mounting ears. All electrical and pneumatic connections appear complete. Internal seals and calibration remain as taken from the vehicle and should be verified by the installer as part of standard workshop procedure.
Compatibility (guideline only):
• MAN TGS Euro 6 – front EBS pressure valve, various axle and chassis variants.

Always match by part number 81521066067 or 81.52106-6067 / K050211 to ensure correct fitment. If in doubt, compare with your existing valve or consult a MAN dealer with your VIN.
