PURPOSE: A butterfly valve inspection apparatus is provided to ensure a quality verified butterfly valve by easily testing stable control of high temperature and high pressure fluid. CONSTITUTION: A butterfly valve inspection apparatus comprises a pipe body(20), a temperature sensor(30), a pressure sensor(40), a heater(50), a pump(60), and a controller(70). The pipe body is equipped with a valve on one end and blocked on the other. The temperature sensor measures the internal temperature of the pipe body. The pressure sensor measures the internal pressure of the pipe body. The pump provides pressure to increase the internal pressure of the pipe body. The controller controls the pressure sensor and the temperature sensor.
