In the process industry, there is nothing more stressful than unexpected downtime that can affect business revenue. Pressure relief valves are the last line of defense to prevent a catastrophic event from occurring. Allied Valve’s top priorities are safety, plant reliability, and preventative maintenance (PM) planning and valve operation training. With years of hands-on experience and data backing us up, it is clear to us that a structured PM program including, testing, and a VR repair program can assist in ensuring all valves will work as designed in an overpressure condition.

How often should pressure relief valves be inspected?

We get this question a lot! There is no one correct answer for every valve or application. Inspection frequency should be based on previous testing and repair history for every valve. If during inspection, valves are found to be defective or damaged, intervals should be shortened until acceptable results are obtained. Valves should also be inspected more frequently if test results are inconsistent. Conversely, if a valve consistently passes testing, inspection intervals can be stretched.

How do I keep track of testing, PM and inspection schedules for multiple valves in our plant?

Allied Valve recommends using ValvKeep, our privately accessed, cloud-based, valve software. ValvKeep is used to manage PM schedules for testing, and VR repairs of every valve in your plant. The software simplifies the maintenance data management process, helps manage repair process workflow, and identifies trends in valve operation and maintenance.

What is VR Repair for pressure relief valves?

A VR stamp signifies that an organization has earned a National Board Certificate of Authorization to repair pressure relief valves in the shop and/or in the field back to like-new condition. Allied Valve holds one of the longest-standing VR Stamps for valve repair in the country. Our technicians undergo thousands of hours of on-site factory training and recertification to deliver the safety and efficiency you need.

Do I have to wait for a valve to fail before scheduling a VR repair?

No! A VR repair can identify wear on parts, galling between sliding surfaces, internal corrosion, or fouling. We have seen internal damage on parts for valves that have passed “functional only” tests, that by code are valid. Once the valve is put through the paces of VR repair, it can show wear and tear that a functional test cannot. Another benefit of using ValvKeep is its ability to help develop predictive repair dates. With this technology, you will be more likely to catch a “bad actor” pressure relief valve before it fails.
