First, the pneumatic valve lined diaphragm overview

Pneumatic diaphragm valve lined by the diaphragm valve and pneumatic actuator composed of two parts, it is compressed air as a driving force, the actual flow of the medium in the process of regulating the flow of media. Pneumatic fluorine fluorine diaphragm valve due to the structure of the valve with a corrosion-resistant liner and corrosion-resistant diaphragm, no stuffing box structure, the throttle element is flexible diaphragm, valve body smooth, so the pneumatic diaphragm diaphragm valve has a negative force Small, high flow, no leakage and convenient and reliable, fire and explosion-proof advantages, pneumatic valve lined with fluorine diaphragm valve widely used in industrial automation systems of strong acid, alkali, strong corrosion, high viscosity, with grain, with fiber and toxic and Not allow pollution of the media flow regulation.
