Chief Features
The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance;
The sealing surface is welded with Co-based cemented carbide, which is wear-resistant, corrosion resistant, good friction resistance and long service life;
The stem is quenched and tempered, and its surface is treated by nitriding treatment, thus it has good corrosion resistant and friction resistant.
It has double seal capability,thus it’s more reliable;
The stem show the position of lift,thus it is more visualized.
