Fisher™ EZH 和 EZHSO 系列

EZH（弹簧关闭式）和 EZHSO（弹簧开启式）系列调压器是精确先导式压力平衡型软阀座调压器。 这两种调压器用于高压天然气输送/城市门站、大流量分输系统和发电厂的气源供应。 它们具有运行平稳可靠、关断严密和使用寿命长等优点。广州奥丽斯特燃气设备有限公司是美国FISHER产品华南区域（广东省）艾默生集团授权代理商。2020美国FISHER技术选型020*叁贰贰0162张S中国费希尔调压网www.zgfisher.com 【张工15876552411手机同微XIN】

功能

完全无大气排放—利用先导式控制系统将所有气体排放至下游系统，因此不会将任何有害废气排放至空气中。

气密切断—锐利的金属塞和软阀座提供气密切断，可用于终端系统等需要正压关闭的应用。

在严酷的工况下具有很长的使用寿命—金属塞设计可使颗粒和碎屑偏离软阀座，提供卓越的颗粒侵蚀阻力，延长使用寿命。

故障模式选项—可以利用 EZHSO 型弹簧开启式设计实现最长的正常运行时间，利用 EZH 型弹簧关闭式设计保护下游资产。 对很多客户来说，通过 EZHSO 型调压器和 EZH 型监测器融合这两种技术可以让这两种装置发挥出最大功效。

精确压力控制—无论负载或入口压力如何变化，都能够提供稳定、精确的下游压力控制。

安静运行—Whisper Trim™ 阀笼选件可以降低多达 8 dBA 的源头噪声，因此无需投入大量成本进行管路处理，例如绝缘、埋阀和使用只会屏蔽噪声的外壳。

完整的压力等级—1500 psig/103 bar 相等的入口和出口压力等级，更易选择，无需特殊的启动或关闭程序。

集成式快速切断配置—当出现过压和失压时，EZHOSX 和 EZHSO-OSX 型通过关闭气体停止供气。

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.

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.
