1)
The product features a reasonable structure, reliable seal, good
performance and nice modeling.
2)Co
hard alloy welded sealing surface, which is wearing resistant,
erosion proof, abrasion proof and long-lived.
3)The
surface and the adjusting media of the valve shaft are nitrogenized
so that it is erosion and abrasion resistant.
4)PN≥*5.0Mpa(class**0),
the middle cavity uses a self-tightening sealing structure to have
the sealing performance reinforced along with the pressure rise so
as to ensure the sealing performance.
5)There
is no backward sealing structure in the valve, so the sealing id
reliable.
6)The
material of the filling and the flange size can be chosen and
matched according to the applications and the requirements of the
use’s. That can satisfies all kinds of working requirements.
