Description

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.

APPLICATION

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.

FEATURES

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