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

Since the beginning of our business, we have had three primary goals to accomplish. These goals have been the basis of our success over the past decades.

These goals are:

• Kelley® produces only the highest quality orifice plates at competitive prices.
• Our quick delivery time results in less downtime, less cost, and higher satisfaction for our customers
• We only sell through reputable distributors who are knowledgeable about the requirements of the natural gas industry, and who maintain only the highest standards of excellence.
