Pilot operated pressure sustaining valves PS47

ADCA's PS47 piloted pressure sustaining valves are designed for use with steam, compressed air, nitrogen and other gases compatible with materials of construction. The PS47 accurately senses upstream pressure and acts to minimize or disperse excess pressure.

  • Precise upstream pressure control from 0.07 bar to 17 bar.
  • Rugged steel or stainless steel construction.
  • Guided piston and valve stem.
  • Hardened plug.
  • Soft plug.
  • Low pressure top.
  • Dome version.
  • Bottom cap drain connection.
  • Stellited plug and seat.
  • External sensing connection.

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

  • PS47 - steam steel versions.
  • PS47i - stainless steel steam versions (only available from DN 15 to DN 50).
  • PS47G - steel versions for compressed air and gases.
  • PS47Gi - stainless steel versions for compressed air and gases.

  • 1/2" to 2"; DN 15 to DN 50.

  • Flanged EN 1092-1 PN 40.
  • Flanged ASME B16.5 Class 150 or 300.
  • Female thread ISO 7 Rp or NPT.
  • Socket weld (SW) ASME B16.11.

  • Horizontal installation.
  • See IMI - Installation and Maintenance Instructions.
  • In steam applications, a "Y" strainer, moisture separator and steam trap must be installed upstream of the valve.
