Valve Repair, Testing, and Maintenance: Onsite and On-Demand

• Pressure Relief Valve Certified Testing
• National Board Accredited VR Program


Problem: Turnaround downtime can eat you alive.

In this competitive economy, the difference between a profitable oil & gas processing plant and a marginal one depends on efficiency and availability. So more than ever, reducing valve maintenance labor costs and downtime become critical to your bottom line.

As a result, the mobile valve repair shop has become a necessity to adjust to the demands of outage schedules and the need for skilled, certified valve technicians deployed on-site. Instead of transporting valves from each gas processing site to a remote repair location, leading processors want their testing and repair services on-site and on-demand.

To respond to this industry need, Midwest Valve Services (MVS) has launched its newly redesigned and equipped Mobile Valve Shop as an extension of their certified valve repair facilities located in Mandan (ND), Wausau (WI), and Minooka (IL). The 53-foot trailer is fully equipped with specialized tools and equipment to perform valve testing, repair, and maintenance. The MVS Mandan shop is authorized by the National Board of Boiler and Pressure Vessel Inspectors to provide ASME Section I and VIII testing and repair of pressure relief valves in steam, air/gas, and liquid applications.
The MVS mobile valve shop provides the flexibility to accommodate unplanned repairs and make turnarounds more efficient. On-site machining, testing, and diagnostics capabilities minimize or eliminate unnecessary travel to remote locations to perform certain activities. The new trailer is self-sufficient and fully equipped with  almost everything a valve technician needs, including power generation and compressed air.
