Previous: Steel Swing Check Valve
DIN swing flanged check valve depends on flow of medium to open or close. It is used to avoid back flow of medium
Characteristics:
1. Having compact structure, reliable sealing, beautiful modeling
2. The seal face is made of cemented carbide, having wearing resistance, corrosion resistance and long service life.
3. The stem has been tempered, having good corrosion resistance and wearing resistance.
