working principle

This model uses compressed air to push the piston in the pneumatic actuator up. The piston rod and the valve stem are connected by a positioning card. At the same time, when the air compression pushes the piston in the pneumatic actuator up, the valve stem is moved upwards, that is, the valve. Open. When the air compression is lower than the spring force or no gas compression, the piston is pushed by the spring under the action of the spring, and the valve stem is moved downward to close the lower valve port. It is mainly used for fluid cut-off in pipeline systems and is used in pipeline systems.
