New Fisher regulator series and trim options maximize uptime and reduce noise output
June 16, 2010
Emerson has released the Fisher EZHSO Series Regulator as well as Whisper Trim Cage options to the EZH and EZHSO Series. The EZHSO design incorporates a spring cartridge that offers a fail-to-open alternative, ensuring gas delivery and maximizing uptime. The Whisper Trim Technology provides efficient noise prevention at the source and the cage can be easily retrofitted in the field.
The Type EZHSO and EZHSO-OSX (slam-shut) regulators are available in 1, 2, and 3-inch sizes. These new offerings provide the same benefits as Emerson’s proven Fisher Type EZH regulators such as:
- True no-bleed design: Environmentally friendly design eliminates emissions for higher pressure pipelines
- Top-entry maintenance: Reduces time and expense for training, installation and maintenance
- Bubble-tight shutoff: Reduces cost of ownership by precisely regulating high-pressure transmission lines, providing consistent reliability of gas delivery and shutoff
- 1500 psig (103 bar) inlet/outlet rating: Meets higher system requirements
The Whisper Trim Cage option is available for 2, 3, and 4-inch sizes, opening a broader application range for this product family. Noise reduction of 10 - 20 dB(A) can be achieved, depending on the application. As a “source treatment,” the Whisper Trim Technology utilizes multiple orifices of special size, shape, and spacing, which reduces noise-producing interactions and offers a better alternative than path treatment or buried service. Units already installed can be easily retro-fitted with a Whisper TrimCage.
