MAN TGA/TGS/TGX Pressure Limiting Valve 81521016269 4750103000 Brake Euro 6 Horn Valves & Pulls

Description:
This listing is for a genuine MAN/Wabco brake pressure limiting valve assembly with integrated pressure filter bowl and MAN pressure sensor. It is used in the compressed air brake system to limit and control delivery pressure to downstream circuits, protecting components and ensuring stable braking performance. OEM references on the unit are MAN 81.52101-6269 / 81521016269 and WABCO 4750103000, with an additional screw-in pressure sensor marked MAN 81.27421-0251. According to manufacturer and aftermarket catalogues, this valve is used on a wide range of MAN commercial vehicles including TGL, TGM, TGA, TGS and TGX trucks, as well as various MAN bus and coach platforms.

The valve is a pneumatically operated pressure limiting / pressure control valve, typically set to an outlet pressure of around 8.5 bar with an adjustable working range of 5.8–10.8 bar and M22x1.5 VOSS ports. The body is mainly aluminium and steel with a black plastic filter bowl and integrated drain screw. This particular unit is supplied complete with the original MAN 81.27421-0251 pressure sensor and short hose tails as shown in the photos.

The part was removed from a running vehicle; the braking system was checked before dismantling and the valve functioned correctly with no reported faults. After removal the assembly was visually inspected, light cleaning was performed and the ports were capped or taped to keep out contamination. As with any used brake component, we recommend installation by a qualified workshop; basic system checks and leak tests should be performed after fitting, and the vehicle should be road-tested to confirm correct operation. No additional programming is normally required because this is a purely pneumatic/mechanical valve, but workshop procedures should always be followed for the specific MAN model.

This is a genuine MAN/Wabco component, not a low-cost copy. Using original equipment parts helps to maintain braking performance and reliability compared with cheaper aftermarket alternatives. The item comes as pictured, without extra brackets or mounting bolts.
