Pressure Measurement & Control

Ratio Reducing Valves Code 61

The Conflow Code 61 -Ratio Reducing Valve is used to provide a reduced downstream fluid pressure. The valve is made to a fixed ratio, to reduce the upstream pressure by a set proportion, making no allowance for inlet pressure variations.

This valve is used where the inlet pressure is basically constant or where pressure reduction is required but does not need to be closely maintained.

Typical Applications

  • To reduce the water mains pressure in underground mines at the shaft bottom before distribution throughout the mine. This is particularly useful in deep mines where the pressure head is high or where the pipe systems are not suitable for high pressures
  • To control pressure in fire fighting systems

Features

  • 1/2", 1", 1 1/2", 2", 3" and 4" sizes available
  • Maximum working pressure 105 bar
  • High Pressure Units up to 350 bar (1/2”) and 206 bar (1”)
  • Ratio reduction from 1.1:1 to 20:1 of inlet pressure
  • Suitable for use with water and oil
  • Compact in-line fitting
