Pharmaceutical Diaphragm Valve Manufacturers

Diaphragm valve is a special type of shut-off valve, which uses a flexible diaphragm as a closing element to isolate the inner cavity of the valve body and the fluid. Diaphragm valves are widely used in pharmaceutical, food, biotechnology, chemical and other industries with their simple structure, excellent sealing performance and high adaptability to the medium. The fluid is completely isolated from the valve stem, valve cover and other components to avoid contamination. The inner cavity is smooth and has no dead corners, which is suitable for industries with high cleaning requirements. The diaphragm directly contacts the valve seat to achieve a good closing effect. It effectively prevents external leakage and internal contamination. The switch is controlled by manual, pneumatic or electric actuators, which is easy to maintain. The valve body material is forged S31603. The diaphragm material (such as TFM+EPDM) can be selected from special alloy materials (such as titanium, Hastelloy, 904L, etc.), which are suitable for various corrosive media. The flow channel is designed as straight-through or multi-pass type to reduce fluid resistance and reduce material residue.
