Fisher Type 63EG-98HM
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.
