Pilot control globe valve (PCGV) can use the pressure difference produced by fluid itself to realize the opening and closing states with a pilot valve. In this paper, numerical method is used to investigate the fluid flow characteristics and the valve core movement inside PCGV under different opening and closing times of pilot valve. The result shows that, shorter opening and closing time of valve core results in the shorter vibration of valve core as well as the stronger unstable fluid in main valve and faster opening and closing process of PCGV. Longer opening and closing time of valve core can do less damage to valve body. This work can give some guides for the optimal design work of PCGV and someone who are researching on valves with similar structures.
