Abstract: The disclosure relates to a fluid valve including a lip seal having a sealing lip between a pressure inlet and a pressure outlet, wherein the position of the sealing lip can be varied to vary a passage cross section. The disclosure further relates to a pneumatic valve arrangement having a park release valve and the fluid valve. The disclosure further relates to a pneumatic braking system including the fluid valve or the pneumatic valve arrangement.

Abstract: A brake modulator (1) for a compressed air braking system (80) of a vehicle is disclosed. The brake modulator (1) has a main housing (8) and two relay valves (2, 3). Each relay valve is configured with a delivery valve seat (31, 131) and a vent valve seat (30, 130) and a vent position, wherein compressed air inlets (2d, 3d) are connected via a transverse bore (27) to a common compressed air inlet port (25, 26), and a delivery duct (12a, 112a) extends in the axial direction (A) in each relay valve (2, 3). The relay valves (2, 3) have guide body inserts (12, 112) which are inserted into a longitudinal bore (29) of the main housing (8), which longitudinal bore (29) extends in the axial direction (A), and the relay valves (2, 3) in each case have the delivery duct (12a, 112a).
