Pilot operated pressuere reducing valve PRV47 DN15-50

ADCA PRV47 pilot operated pressure reducing valves are designed for use with steam, compressed air, nitrogen and other gases compatible with materials of construction.

PRV47 can be installed in pressure reducing stations, in all industries, and provide sensitive and accurate control even when inlet pressure fluctuations or relevant flow variations occur.

  • Accurate control of downstream pressures from 0.07 bar to 17 bar.
  • Robust steel or stainless steel construction.
  • Suitable for dead-end conditions.
  • Guided piston and valve stem.
  • Hardened plug.
  • Soft sealing.
  • Low pressure top.
  • Dome version.
  • Bottom cap drain connection.
  • Stellited plug and seat.
  • Internal sensing line.

  • Saturated steam, compressed air and other gases (group 2) compatible with construction (except oxygen).

  • PRV47, PRV47E - steel steam versions.
  • PRV47i, PRV47iE - stainless steel steam versions (only available from DN 15 to DN 50).
  • PRV47G, PRV47GE - steel versions for compressed air and gases.
  • PRV47Gi, PRV47GiE - stainless steel versions for compressed air and gases.
  • Suffix E: Version with solenoid valve for remote shut off.
  • PRS: All above models are available with optional lift valve pilot, e.g. PRS57G (see fig. 8).

  • 1/2" to 2"; DN 15 to DN 50.
