Description
1. Middle cavity of valve adopts hte pressure sealing strucuture, the high medium pressure, the better sealing property.
2. Two end of branch pipe is welding connection. It is suitable for different connection requirement.
3. The withstand pressure parts of valve chooses the excellent alloy steel. It has the advantages such as good high temperature performance, high bearing pressure, safe and reliable property.
4. Sealing face of valve flap and valve base adopts the STL cobalt base hard alloy welding to form. The sealing face hardness is high and it has advantages of anti-abrasion, anti-high temperature, anti-corrosion, scraping proof and long service life.
5. Valve flap turns around the pipe out valve base. It can reduce the impulse when closing.
6. Pin structure is installed inner. It can reduce the leakage.
