Ensure PRV Safety Through Regular Inspections and Preventative Maintenance.
It's important for organizations to establish a comprehensive pressure relief valve maintenance program that includes regular inspections, testing, and certification based on applicable codes and standards. The National Board Inspection Code (NBIC) provides guidelines for the certification and testing of pressure relief valves. Adherence to these guidelines helps ensure the ongoing safety and reliability of pressure vessels in various industrial applications.
As a VR Certificate of Authorization and VR Stamp holder, Midwest Valve Services is authorized to provide ASME Section I and VIII testing and repair of pressure relieve valves in steam, air/gas, and liquid applications. The VR stamp serves as certification that our repair work has been conducted in compliance with established standards, and that we are qualified to do the proper repair of your relief valves. Look to Midwest Valve Services to conduct your next annual PRV inspections or other recertifications.

With our on-demand service for PRV pick-up and return, we’ll make your PRV certification process as easy as possible.

AccuTEST Safety Valve Test System

AccuTEST is the only in-line safety valve test system on the market that can perform an acoustic seat leak test. Without isolation valves or a bypass, some safety relief valves can only be tested during a shutdown. If scheduled testing intervals fall between planned shutdowns, plant personnel are faced with a difficult decision. Do they shut down the unit to test the valves, potentially losing millions of dollars in production? Or, do they extend the inspection interval until the next shutdown, hoping the valve performs when called into action? With AccuTEST, reliability engineers, inspectors, and maintenance planners do not have to make those decisions. We can perform a set pressure verification and seat leakage test in-line and provide decision makers with the critical data they require to safely extend an interval until the next scheduled shutdown.
The AccuTEST Safety Valve Test System is a fully automated in-situ test system that utilizes a computer-controlled electric motor in conjunction with system pressure to verify set point. AccuTEST accurately determines if a valve lifts within set point tolerance and if the valve seat is tight, giving you the peace of mind that your safety relief valves will perform when needed and protect your plant assets and personnel.
