The fluid dynamics of butterfly check valves have a crucial impact on their performance. During the opening and closing process of butterfly check valves, the fluid will form a complex flow path in the valve body, especially near the valve plate, which is prone to eddy currents, turbulence and fluid bypass. These flow phenomena not only increase the pressure loss of the system, but also may cause erosion and wear of the sealing surface, thereby affecting the life and sealing performance of the valve.
