HAND BRAKE VALVE, PNEUMATIC BRAKE SYSTEM, VEHICLE, METHOD OF ASSEMBLING A HAND BRAKE VALVE

The invention relates to a hand brake valve (100) for actuating a parking brake (700) and/or an auxiliary brake (702) of a vehicle (1000), in particular a commercial vehicle (1002), and a method of assembling the hand brake valve (100). The hand brake valve (100) comprises: - a valve cartridge (120) comprising a cartridge locking feature (126), wherein the valve cartridge (120) is adapted to accommodate a valve piston arrangement (180) with a valve piston (182) and a valve seat element (136), wherein - the valve seat element (136) is movable in an axial movement (MA) along a valve axis (AV) against a valve stop (124) of the valve cartridge (120). In accordance with the invention, the hand brake valve (100) further comprises: - a valve guide element (140) with a guide body (146), adapted to limit the axial movement (MA) of the valve seat element (136), wherein - the valve guide element (140) comprises at least one guide locking feature (142), adapted to create a positive lock (PL) with the cartridge locking feature (126), wherein - the positive lock (PL) is established by a locking movement (ML) of the valve guide element (140) into a locked position (LOP), and - the hand brake valve (100) comprises at least one snap lock element (144), adapted to secure the valve guide element (140) in the locked position (LOP).
