Features

1. Product design is in accordance with NB/T47044-2014 and ASME B16.34-2013 standards:
2. The valve stem has been tempered and nitrided, and has high temperature resistance, wear resistance and good corrosion resistance.
3. Anti-scouring valve seat, valve disc and anti-scouring sleeve are all nitrided and have scouring resistance. They are replaceable accessories.
4. The medium flow direction adopts high inlet and low outlet, which has the characteristics of small opening and closing torque and easy opening.
5. The valve seat and valve disc sealing surface are made of cobalt-based hard alloy surfacing or plasma spray welding, which has good high temperature resistance, wear resistance and abrasion resistance.
6. The valve body adopts forging structure.
