Natural gas pressure regulator EZH series

pistonsingle-stagehigh-pressure

EZH (Spring-to-Close) and EZHSO (Spring-to-Open) Series regulators are accurate pilot-operated, pressure balanced, soft-seated regulators. They are designed for use in high pressure natural gas transmission/city gate stations, large capacity distribution systems, and power plant feeds. They provide smooth, reliable operation, tight shutoff and long life Features 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.
