August 3, 2011 – Emerson Process Management released the 4-inch Fisher EZHSO Series spring-to-open pressure reducing regulator. The EZHSO design incorporates a unique spring cartridge that offers a fail-to-open alternative, ensuring gas delivery in the event of diaphragm failure or lack of supply pressure to the pilot. The failure action is the opposite of the EZH Series spring-to-close pressure reducing regulators. The Types EZHSO and EZHSO-OSX (slam-shut) regulators are available in 1, 2, 3, and 4-inch sizes. These new offerings provide the same benefits as Emerson’s proven Fisher Type EZH regulators such as true no-bleed design, top-entry maintenance, bubble-tight shutoff, and inlet/outlet rating of 1500 psig (103 bar).
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.
