Pressure Relief Valve Testing

We’ve designed our Pressure Relief Valve testing service to be as convenient and hassle-free as possible. Whether you prefer on-site testing at your location with our fully equipped mobile units or need comprehensive service at our Casper, Wyoming facility, we’ve got you covered. Our team can handle PRVs of all sizes, from ¼” to 8”, and across a range of applications, including air, gas, liquid, and sour gas. No matter the manufacturer, we’re here to ensure your valves are tested, repaired, and functioning at their best—making it easier for you to focus on your business without worrying about equipment reliability.

Our comprehensive PRV testing services include:

  • In-House and On-Site Testing: Convenient testing options available either at your location or at our Casper facility.
  • Multiple Applications: Testing for air, gas, liquid, sour gas, and more.
  • Expert Repair and Recertification: We handle repairs, conversions, testing, and recertifying of PRVs, ensuring they meet all regulatory requirements.

Each PRV is tested three times to ensure accuracy, and the average result is recorded in detailed test reports. Upon successful certification, valves are sealed, tagged, and reports are delivered. For added convenience, customers can opt for LeakTrak, which allows for easy access to valve reports whenever needed.
