Testimonials

When I came to Shintech over twenty years ago, we were experiencing constant valve issues with our vinyl compressors.  We turned to Mark's Machine at that time to help us solve our recurring valve failures.  Together we worked to install Mark's new compressor valves and our troubles went away immediately.  We have now operated all of our vinyl compressors for over twenty years with Mark's valves and have expanded their role in the repair of other compressor parts.  It's been a very trusting and beneficial relationship for both Marks's Machine and Shintech.

Sincerely,

About three years ago, we were having problems with compressor valves on an offshore Superior compressor. The compressor was in a natural gas service that had liquids and solids entrained. After numerous valve failures and much unit downtime, in the summer of 2005 we installed MPV valves provided by Mark’s Machine in El Campo, Texas. Since this installation, we have not experienced any problems or downtime on the unit due to compressor valves.

In the past 3 years we installed the MPV valves on 5 other offshore compressors, including Joy and Worthington models, and all are performing very well. We are considering installing the valves on other units as well.

These valves are designed to run in normal, as well as extreme (excess fluids, entrained solids, etc.), service conditions. Due to its design, it also provides increased efficiency and cooler temperatures due to less pressure drop through the valves.

The installation of the MPV valves has saved our company tens of thousands of dollars in compressor valves, parts and downtime. To date, our experience with the valves has been excellent.
