Types EZH (Spring-to-Close) and EZHSO (Spring-to-Open)
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.
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
underpressure (OPSO/UPSO) protection.
Type EZHSO-OSX: Type EZHSO with a Type OS2 slam-shut
device for overpressure (OPSO) or overpressure and
underpressure (OPSO/UPSO) protection.
