A hydraulic valve assembly (1) for a work vehicle (10) comprises a fan and a brake function module (1000). A first pump (61) supplies hydraulic pressure to a fan circuit (30) and first and second service brake circuits (21, 22) of a vehicle. The second pump (62) provides hydraulic pressure to a steering and working function module, which in turn provides hydraulic pressure to a steering circuit (50) and a working function circuit (40) of the vehicle. The hydraulic valve assembly may also include a work control module (3000) and an auxiliary module (4000). The modules of the hydraulic valve assembly are detachably connected together via an interface surface (1100, 2200, 2300, 3400, 1500, 4600). 一种用于工作车辆(10)的液压阀组件(1)包括风扇和制动功能模块(1000)。第一泵(61)向车辆的风扇回路(30)以及第一和第二行车制动回路(21、22)供应液压。第二泵(62)向转向和工作功能模块提供液压，该转向和工作功能模块又向车辆的转向回路(50)和工作功能回路(40)提供液压。液压阀组件还可包括工作控制模块(3000)和辅助模块(4000)。液压阀组件的模块经由界面表面(1100、2200、2300、3400、1500、4600)可分离地连接在一起。
