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.
- 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
