Dust suppression

Spray Control Valves Code 100

The Conflow Code 100 - Spray Control Valve is capable of controlling the flow of any fluid by mechanically sensing belt movement, without the need for an independent power supply.

This is achieved by a drive wheel in frictional contact with the moving conveyor belt.

The rotating wheel generates hydraulic pressure to open an ON/OFF valve built into the unit. The valve can be positioned so that the wheel only contacts the belt when loaded, ensuring the valve is only open when necessary, avoiding overwetting, belt slip and soft ground.

Typical Applications

  • Supplying dust suppression water onto conveyer belts transporting mineral, particularly at a transfer point, where one conveyer discharges its contents onto a second belt, and dust is often created.
  • Ideal in applications where there is no electrical or other source of power.
  • Perfect for supplying water sprays on bottom belts where fine dust has accumulated.
  • 1” Unit available for washing purposes.


  • 1/2" Standard and large volume units.
  • 1” Unit available on special request.
  • Maximum working pressure 105 bar.
  • 4" or 6" driving wheels.
  • No additional power supply is needed.
  • Operates at belt speeds from 0.5 M/sec (100 ft/min) to 3.75 M/sec (750 ft/min)
