A four-way valve assembly provided with a housing having an elongate bore in which a single shiftable valve is slidably disposed. The housing has a main center part and a pair of end parts attached to opposite side thereof. A pair of sleevelike liners are disposed in the bore, and an inlet port communicates with the bore in the region between adjacent inner ends of the liners. A pair of load ports communicate with the bore through the individual liners and are spaced axially on opposite sides of the inlet port. A pair of exhaust ports are provided, one in each end housing part, for communication with the bore. The single valve has an elastic poppet mounted centrally thereof and disposed to axially shift between and sealingly coact with valve seats formed on the opposed inner ends of the liners. Each liner has a sleevelike hub part at its outer end which is received within the bore of the respectively adjacent end part so that the latter is concentrically seated on the hub part.
