The bronze commissioning range offers accuracy of +/-5% on all settings. The integral fixed oriface design offers greater accuracy, makes set-up easier and involves fewer connections reulting in lower installation costs.

Features & Benefits

  • The Double Regulating Valve offers an accuracy of ± 5% on all settings for precise flow regulation
  • Y-Pattern globe valves with characterised throttling disc tending towards equal percentage performance.
  • Double regulating feature allows valve opening to be set with an Allen key
  • Operation of the valve is by means of the Microset handwheel
  • WRAS approved
  • The D921 has sufficient authority to give effective regulation over the range of flows covered by matching flow measurement devices/valves
  • The D923 low flow regulating valve has an authority matched to the range of ultra-low flows covered by the D902 flow measurement device
