Type 63EG-98HM Pilot-Operated Relief Valve or Backpressure Regulator 

Type 63EG-98HM can be used for gas, liquid, or steam applications. For applications up to 550°F / 288°C, the Type 63EG-98HM utilizes high temperature Ethylenepropylene (EPDM) or Perfluoroelastomer (FFKM) for class VI shutoff. If used in a corrosive service, Perfluoroelastomer (FFKM) and other elastomers are available options that offer superior resistance to heat and most corrosive chemicals.

When using the Type 63EG-98HM with a corrosive liquid, usually water or a water-containing solution, the valve materials must be selected with care. For aqueous solutions, use a stainless steel linear cage or Whisper Trim III Cage and body flange to ensure valve plug travel on a corrosion-free surface.
