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.
The EZHSO Series is now available in 4-inch size providing the same benefits as the 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 EZH/EZHSO Wide Open Monitor Configuration ensures regulated gas delivery downstream. This configuration offers typical monitor overpressure protection and also provides underpressure protection by ensuring a predictable failure mode of the downstream working regulator.
