Product Description

1. Rational structure, reliable sealing, excellent performance, pretty appearance. 2. Co-radix alloy welded sealing surface, anti-wearing, erosion-proof abrasion-proof and longer use life. 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 wnsure the sealing performance. 5. There is no backward sealing structure in the valve, so the sealing is reliable. 6. The materials of the filling and the flange size can be chosen and matched according to the applications and the requirements of the user's. That can satisfies all kinds of working requirements.
