The invention relates to a magnetic powder brake type testing device of a large-torque electric actuator for a valve. The testing device comprises a support, a pulling and pressing sensor component, a force arm component, a magnetic powder brake, an optical-electricity encoder component, a closed-type transmission mechanism and a control box of a programmable logic controller (PLC). The magnetic powder brake is fixed on the support. An output shaft of a tested electric actuator transmits torque to the magnetic powder brake through the closed-type transmission mechanism. A connecting disc of the tested electric actuator is fixed with the force arm component. The pulling and pressing sensor component is connected with a force arm rod of the force arm component in a 90-degrees mode. The optical-electricity encoder component is respectively connected with a main shaft of the closed-type transmission mechanism and the control box of the PLC. The testing device is compact in structure, high in test precision, low in production cost, capable of conveniently and accurately measuring and displaying the torque, travel, a rotation speed, case analysis of service life test and the like of the tested electric actuator in real time, and especially suitable for testing of the electric actuator with large torque of 12000Nm.
