Custom Pneumatic UPVC Flange Diaphragm Valve Suppliers, Factory, Manufacturing Company

The pneumatic UPVC flange diaphragm valve is constructed from UPVC material, which resists strong acids and alkalis and does not rust or scale, making it suitable for handling various corrosive media. The valve body has a compact structure, is lightweight, and is easy to install and maintain, reducing the load on the piping system. The diaphragm structure ensures a tight seal, effectively preventing media leakage and ensuring the system's safe and stable operation. Pneumatic control enables rapid switching, responsive operation, and easy remote control and automation. The material complies with national hygiene standards, making it suitable for food and pharmaceutical applications requiring high hygiene standards.

It adopts a corrosion-resistant valve body and corrosion-resistant diaphragm, no stuffing box structure, the throttling element is elastic diaphragm, and the flow channel of the valve body is smooth. Therefore, the pneumatic membrane diaphragm valve has the advantages of low stress, large flow, no external leakage, convenience, reliability, and fire and explosion prevention. It is widely applicable to weak acid, weak alkali, weak corrosion, high viscosity, containing particles and Flow regulation with fiber and toxic and nonpolluting media.
