Rate Usage Filed
Emerson Fisher Make EZR Series Pressure Reducing Regulator
Fisher Make Type EZR pilot-operated, pressure reducing regulator
designed to give accurate, smooth, quiet operation, tight shutoff,
and long life, even in dirty service. EZR Series can be installed

facilities. The Type EZROSX is available with a slam-shut device
which provides overpressure protection and/or under pressure
protection by completely shutting off the flow of gas to the
downstream system.
