Model 9100 Extension Process Control Valve


The ORION® Series 9100 bronze control valve is available with a Stainless Steel bonnet extension for cold service to –325° F
(–198° C), see ASME/ANSI B16.24. This option uses the standard bronze bonnet with a removable extension made of 316SST:

  • Available in a short 4 in. (101 mm) or long 6 in. (152 mm)
    extension (SST portion).
  • Standard packing is a single set of PTFE chevron rings with live
    spring loading.
  • Mounting brackets are available for use in
    high-vibration applications.


This option is suitable for cold, non-corrosive liquids and vapors, whenever external icing is possible or when the packing must be insulated from the cold fluid passing through the valve body.


The stainless steel extension is a superior insulator, compared to conventional bronze extensions, due to its greater strength and
resistance to heat transfer.
