Check valve
Structure advance and feature
1. The design of product according too regulation of ANSI B16.34 and E101 standard, it owns the advantage of suitable structure, excellent property, graceful appearance.
2. Middle cavity of valve adopts the pressure self-compaction sealing structure, the higher medium pressure, the better sealing property.
3. Two ends of branch pipe is welding connection, it is suitable for different connection requirement...
4. The withstand pressure parts of valve chooses the excellent alloy steel, It has the advantage such as good high temperature performance, high bearing pressure, safe and reliable property.
5. Sealing face of valve flap and valve base adopts the STL cobalt base hard alloy bead welding to form, the sealing face hardness is high, anti-abrasion, anti high temperature, anti-corrosion, good proof scraping, the life very long
6. Valve flap turns around the pipe out of valve base, it can reduce the impulse when closing.
7. Inner installation type pin structure, if can reduce the leakage, it is convenient and reliable to operate
