Introduction
The pneumatic soft seal flange butterfly valve series consists of valve body, butterfly plate, valve stem and pneumatic actuator. The pneumatic actuator is driven by compressed air to drive the valve stem to rotate, and the driving butterfly plate rotates 90 degrees to achieve the opening and closing effect. Flange connection, simple structure, easy installation, especially suitable for short installation distance and large diameter pipelines. By selecting different types of pneumatic actuators, it can meet different process control requirements and is widely used in a variety of automatic control pipelines and devices.
