Mobile PSV Units
  • Have a tight schedule or remote site? Let us come to you!

    At Powell, we have two 48’ mobile PSV servicing trailers that are completely self-supported and compliant with Transport Canada. Our insulated and heated mobile units are equipped with: testing equipment which can handle up to 8” inlets and air or liquid testing to 2600 PSI; overhead cranes, fully tooled work stations, 3000 PSI test air compressors, a cleaning station, an electric lathe, lapping equipment and an 8 HP shop compressor.

  • The benefits of a valve shop on wheels are endless, the mobile PSV/PRV unit benefits include:

    • Reinstallation of your valves can be completed immediately after final inspection.
    • Rush testing on valves such as instrument air, fuel gas or boiler can be done immediately, if compliant with local regulations.
    • Overall reduction in your system downtime.
    • Elimination of logistic problems normally associated with shipping and handling.

  • To reduce downtime of your on-site valves, we offer an exchange program that allows our customers to pre-order PSV/PRV valves from our inventory. The exchange valves are re-certified and delivered prior to your shutdown or maintenance cycle so all you have to worry about is the removal and installation of your valves.

    Additionally, we have a rental program that provides you the option of renting a valve.  This is a great program for those that require a valve for a short term, whether it is a day, week or month, saving you the unplanned cost of a new valve.

    We also offer a wide range of additional programs, including the storage of your critical spares and an online documentation portal, which allows you access to your historic inspection reports. To help customize a program that will work for you, please contact us.

  • ​We have no limitations on whose valves we can service, we are able to repair and modify valves from over 600 manufacturers including: Lockwood, Summit Valve, KF Industries, M&J Pipeline Valves, Leser Valve, Farris, Consolidated, Crosby and Cameron. We ensure OEM standards are upheld by providing manufacturer’s comprehensive training to our certified technicians.
