G641F46 Pneumatic Fluorine Lined Diaphragm Valve product details

G641F46 Pneumatic Fluorine Lined Diaphragm Valve summary

G641F46 Pneumatic Fluorine Lined Diaphragm Valve produced and sold by Baigang valve group is composed of diaphragm valve and pneumatic actuator. It is powered by compressed air and can adjust the flow of the fluid medium in the process pipeline.Pneumatic diaphragm valve lining fluorine due to adopt in the structure with corrosion resistant lining of the body and the corrosion resistance of the diaphragm, no stuffing box structure, throttling element for elastic diaphragm, the body flow is smooth, so the diaphragm valve pneumatic film is Yin force is small, large flow, no leakage, and the advantages of convenient and reliable, fire blast, pneumatic diaphragm valve lining fluorine is widely used in industrial automation system of strong acid, strong alkali, strong corrosion, high viscosity, containing clever grain, with fiber and toxic and not allow pollution medium flow control.
