A valve assembly for an aircraft fluid system comprises: a pressure relief valve comprising a blocking member and a pressure relief passage, the blocking member configured to restrict a fluid flow in the pressure relief passage when the pressure relief valve is in a closed configuration, wherein the pressure relief passage is connectable to a fluid passage of the aircraft fluid system to permit pressure relief of the aircraft fluid system when the pressure relief valve is in an open configuration; and an actuator operable in a first configuration and a second configuration; wherein when the actuator is in the first configuration, the actuator is configured to apply an actuation force to the blocking member which forces the pressure relief valve towards the closed configuration; and when the actuator is in the second configuration, the actuation force applied to the blocking member is reduced such that the pressure relief valve is openable to permit pressure relief of the fluid system.
