working principle

This model uses compressed air to push the piston in the pneumatic actuator upward, and the piston rod and the valve rod are connected by positioning cards. At the same time, when the air compression pushes the piston in the pneumatic actuator upward, it also pulls the valve rod upward, so that the sealing surface on the valve seat presses the sealing surface of the upper valve body, that is, the upper valve port connection is closed. When the air compression is lower than the spring force or there is no air compression, the piston will push down under the action of the spring and drive the stem down at the same time to close the lower valve port. It is mainly used for fluid switching in the pipeline system, one in two out switching, and applied to the pipeline system without pollution or mixture.
