Product overview

Relying on the rotation of the valve core to make the valve open or closed, the valve core and the inner side of the valve body are all made of fluoroplastic. It has the advantages of light switch, small volume, reliable sealing, simple structure, easy maintenance, and wide range of use. Adopting full bore and floating ball structure, the valve can be closed without leakage in the whole pressure range. Compact and reasonable structure, the valve body cavity space is minimal, reducing the medium.
