Introduction
Type EZH and EZHSO series regulators
Introduction
Type EZH and EZHSO 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 and reliable operation, tight shutoff and long life.
The EZH and EZHSO Series are in conformity with the Pressure Equipment Directive PED 2014/68/UE and are classifed
under Category IV.
Available Configurations
Type EZH:
Spring-to-Close pilot-operated pressure
reducing regulator for low to high outlet
pressure
Type EZH-OS2:
Type EZH pressure reducing regulator
with an OS2 slam-shut device for overpressure or overpressure and underpressure protection
Type EZHSO:
Spring-to-Open pilot-operated pressure
reducing regulator for low to high outlet
pressure
Type EZHSO-OS2:
Type EZHSO pressure reducing regulator
with an OS2 slam-shut device for overpressure or overpressure and underpressure protection
