The cast carbon check valve is an automatic valve mainly used to prevent fluid backflow. Its working principle relies on the fluid's own power, the weight of the valve disc, and the pressure of the spring. When the fluid flows forward, the valve disc is pushed open, allowing the fluid to pass smoothly. When the fluid tries to flow back, the valve disc quickly closes to prevent backflow.
