Fluorine Lined Pneumatic Bellows Diaphragm Flow Control Valve

Fluorine lined pneumatic bellows diaphragm flow control valve is lined with fluorine plastic inside to improve the valve's corrosion resistance. The valve disc is connected with the actuator through the bellows. When the actuator acts on the bellows, the bellows will deform, thus controlling the opening and closing of the valve disc, and then controlling the flow of fluid.
