The light and small integrated pump valve assembly comprises a space micropump main part, a space micropump backup part, a one-way valve main part, a one-way valve backup part, an assembly outlet, a filter, an assembly inlet, a compensator, a gas adding and discharging valve, an outlet pressure sensor, an inlet pressure sensor and a bottom plate. According to the pump valve assembly, the mechanical pump, the compensator, the filter, the one-way valve, the pressure sensor and the gas adding and discharging valve component are compactly integrated, the mechanical pump in the pump valve assembly can drive a working medium to flow, the mechanical pump has a main pump and a backup pump, a loop channel is automatically switched when the main pump and the backup pump are switched, and an internal loop or short circuit is not formed; the compensator can absorb and compensate a loop working medium, and the pump valve assembly can achieve thermal control of a satellite thermal load of 500W (long term) and can achieve thermal control of 1.5 KW (1-4 hours) in a short time. The integrated pump valve assembly can be widely applied to active thermal control systems of high-power loads, deep space exploration spacecrafts and the like.
