Shutoff Valve


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.

Tips for using shutoff valve pipe

  • In high-rise pumping, the application of shut off valves can prevent concrete backflow.
  • When the concrete pipe is blocked, close the concrete with the shutoff valve first, and then deal with the pipe blockage.


Shutoff Valve Application

Shutoff valve pipe is using for Putzmeister, Schiwng, Sany, Zoomlion concrete pump when concrete delivery.
