1, the sealing is reliable. The driving shaft of the fully open position drives the valve shaft clockwise to 90 degrees. It can remove dirt on the sealing surface by itself, and achieve a sealed and closed angle. It can seal more tightly, and it can also remove the sealing clearance between the sealing surfaces and ensure reliable seal.
2. Corrosion resistance, wear resistance and long service life. When the valve is opened, the drive valve shaft can turn off to a small angle at a small angle. It can be separated and worn, so the sealing pair is heat-treated and grinded. Therefore, it is wear resistant. Suitable sealing material is selected for different media, which can meet the requirements of corrosion and wear resistance.
