The Manufacturing of Orifice Plates is Our Primary Concern

Since July 1975, the staff of Kelley Instrument Machine, Inc. has felt privileged to serve the natural gas industry.  We are proud that the manufacturing of quality Kelley Orifice Plates has never been a side-line business, but our number-one concern.  We work hard to ensure that our orifice plates are the very best quality available.
