The shutoff valve is a device for controlling concrete with isolation and dredging. Shutoff valve is made of 20 steel, which have simple structure, wear resistance and good sealing performance for concrete pump pipe. The surface is painted to prevent rust and corrosion. In the effective use of concrete, shutoff valves play a great role as concrete pump accessories.
Shutoff valve pipe is made of #20 Steel, after quenching treatment, it has high hardness, good toughness and high strength.
