Pressure Measurement & Control

Adjustable Reducing Valves Code 44

The Conflow Code 44 - Adjustable pressure reducing valve provides a pre-determined outlet fluid pressure irrespective of variation of inlet pressure.

The valve operates on a simple throttling principle. The throttle adjustment is achieved by the downstream pressure acting on a spring-loaded piston to open and close the valve. Thus the flow through the valve is reduced and increased as the inlet pressure fluctuates, in order to maintain constant downstream pressure.

Adjustment of the set pressure is carried out by increasing or reducing the spring compression by turning the adjusting screw.

Typical Applications

  • To reduce the water mains pressure to a level suitable for dust suppression in underground mines
  • Pressure reduction for water circuits on cutting machines, i.e. motor cooling circuits, dust suppression circuits and machine mounted fire hoses


  • 1/2", 3/4", 1" and 1 1/4"” sizes available
  • Maximum working pressure 206 bar
  • Low, High and Extra High outlet pressure types
  • Simple screw adjustment of pressure reduction
  • Pressure reduction range up to 124 bar
