EZH & EZHSO Series
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).
Available Configurations
Type EZH (Spring-to-Close): Pilot-operated pressure reducing regulator for low to high outlet pressure
Type EZHSO (Spring-to-Open): Pilot-operated pressure reducing regulator for low to high outlet pressure
Type EZHOSX: Type EZH with a Type OS2 slam-shut device for overpressure (OPSO) or overpressure and under pressure (OPSO/UPSO) protection
Type EZHSO-OSX: Type EZHSO with a Type OS2 slam-shut device for overpressure (OPSO) or overpressure and under pressure (OPSO/UPSO) protection
