Easy Maintenance System
Introduction
Type EZH and EZHSO series regulators
are accurate pilot-operated, pressure bal-
anced, soft-seated regulators.
They are designed for use in high pres-
sure natural gas transmission/city gate
stations, large capacity distribution
systems, and power plant feeds.
They provide smooth and reliable opera-
tion, tight shutoff and long life.
The EZH and EZHSO Series are in con-
formity with the Pressure Equipment
Directive PED 97/23/EC and are classified
under Category IV.
