Type EZR-os2
EZR Series
Pilot-Operated Pressure Reducing Regulators
Introduction
The type EZR pilot-operated, pressure
reducing regulator designed to give accu-
rate, smooth, quiet operation, tight shut-
off, and long life, even in dirty service.
It is also available with a slam-shut
device, the type EZR-OS2, which can
provide either overpressure protection or
overpressure and underpressure protec-
tion by completely shutting off the flow
of gas to the downstream system.
The EZR Series can be installed in various
natural gas applications such as transmis-
sion/distribution systems, industrial and
commercial facilities.
The EZR Series is in conformity with the
Pressure Equipment Directive PED 97/23/EC
and is classified under Category IV.
