[origin: WO2021074663A1] The invention relates to a valve (100) for controlling flow pressurized fluid to a trailer (200) attached to a vehicle comprising a housing (110) including a lateral extension (120) and a guide (124) with a sliding surface (126), a first port (P11) for receiving pressurized fluid from a first source of pressurized fluid, a second port (P22) selectively connected to the first port (P11), wherein the second port (P11) is configured to provide control pressure to brakes provided at the trailer (200). A third port (P12) is provided in the valve (100) that is operably and selectively connected to the first port (P11) and is configured to provide supply pressure to the brakes provided at the trailer (200). Finally, said valve (100) an intermediary valve unit (118) configured to directly facilitate the connection between at least the first port (P11) and particularly, the third port (P12).
