4 way ball valves

The four-way ball valve is a valve that uses a ball as a switch and reversal. It has four channels and can realize mutual isolation and connection between four different channels. The ball can rotate inside the valve, and the opening and closing status of the channel is controlled by different rotation angles. There are four holes on the ball, which correspond to the four channels inside the valve body. As the sphere rotates, the pores and channels can correspond to or be isolated from each other. When the holes of the sphere completely correspond to the channels, the valve is in a fully open state and the medium can pass through smoothly. When the hole of the ball is completely isolated from the channel, the valve is in a fully closed state and the medium cannot pass. When the medium needs to flow to other channels, the ball can be rotated to make the holes correspond to the corresponding channels, thereby realizing the valve reversal.
