Fisher EZH och EZHSO-serien regulatorer

Fisher EZH och EZHSO-serien regulatorer

Fisher™ EZH (Spring-to-Close) och EZHSO (Spring-to-Open) serierna regulatorer är exakta pilotstyrda, tryckbalanserade, mjuksätade regulatorer. De är konstruerade för användning i naturgasöverförings- / stadsportstationer med högt tryck, stora kapacitetsdistributionssystem och kraftverksmatningar. De ger jämn, tillförlitlig drift, tajt avstängning och lång livslängd.

  • Absolutely No Atmospheric Bleed—Eliminates nuisance and wasteful bleed gas to atmosphere by utilizing a pilot-operated control system, which bleeds 100% of the gas to the downstream system.
  • Bubble-Tight Shutoff—A knife-edged metal plug and soft seat provide bubble tight shutoff for use in applications where positive shutoff is required such as dead-end systems.
  • Long Life in Severe Service Applications—The metal plug design deflects particles and debris away from the soft-seat, which gives excellent particle erosion resistance, prolonging service life.
  • Failure Mode Options—The Type EZHSO spring-to-open design can be utilized to maximize uptime while the Type EZH spring-to-close design can be utilized to protect downstream assets. For many customers, combining the two technologies with a Type EZHSO worker and Type EZH monitor incorporates the best of both worlds.
  • Precise Pressure Control—Provides stable and accurate downstream pressure control regardless of load changes or inlet pressure variations.
  • Quiet Operation—The Whisper Trim™ Cage option reduces noise by up to 8 dBa at the source, eliminating the need for expensive path treatments such as insulation, buried valves, and enclosures which only mask noise.
  • Full Pressure Rating—The equal inlet and outlet pressure rating of 1500 psig / 103 bar, which allows easier selection and requires no special startup or shutdown procedures.
  • Integral Slam Shut Configurations—Types EZHOSX and EZHSO-OSX discontinue gas service by shutting the gas off if there is an overpressure or underpressure condition.
