DST Series

Series DST is a pilot operated downstream pressure regulator mainly used for steam service applications. It is used for reducing pressure in piping mains and process applications. It offers higher flow capacities and provides more accurate control than conventional direct operated regulators. Series DST pressure regulators maintain constant downstream pressure even when inlet pressure fluctuates or variation in flow occurs.

  • Maintains downstream pressure within ±10% tolerance band irrespective of variations in inlet pressure and flow.
  • Pressure adjusting can be changed while regulator is in pipeline.
  • Ease of Maintenance as regulator can be inspected without removing body from the pipeline and also pilot can be removed by using only four bolts.
  • Stainless steel internal parts provides extended service life of regulator.
  • Inbuilt Strainer installed on Pilot ensures ultimate protection against dirt and scale.
