Fisher 63EG Series

fisher 63EGFisher Type 63EG pilot-operated pressure relief valves may be used for both liquid and gas service. 

Type 63EG is also suitable for throttling backpressure or bypass applications. The main valves in both constructions use quick-change trim packages for fast maintenance.

Features:

  • Fast pilot reseat
  • Stable startup: the unique hollow valve stem in the pilot provides quick pressure registration on top of the main valve plug, preventing main valve unseating during normal system startup
  • Noise reduction capability
  • Overpressure protection: a superior pump bypass regulator for overpressure protection in pump recirculation applications
  • Low buildup capability: 6358 Series relief valve pilots reduce the buildup required for the main valve to go wide-open
