When it comes to process safety, having pressure relief valves (PSVs) in place is only half the battle. The real question is: are they functioning as they should when needed the most?

Here’s why routine maintenance of PSVs is essential:

🔹 Prevent Valve Sticking: Over time, debris, corrosion, or wear can cause a PSV to stick or malfunction. Routine checks help ensure that the valve will operate smoothly when required.

🔹 Ensure Accurate Set Pressures: PSVs are designed to open at a specific pressure, but over time, calibration can drift. Periodic testing confirms the valve still opens at the correct set point, maintaining system safety.

🔹 Identify Wear and Tear Early: Regular inspection helps you spot damage or corrosion early, preventing unexpected failures and costly shutdowns.

🔹 Compliance with Safety Standards: Industries governed by strict safety regulations (e.g., API, OSHA) require routine PSV inspections to remain compliant. Non-compliance can result in fines, penalties, and even operational downtime.

🔹 Optimize System Efficiency: A well-maintained PSV ensures your system isn’t subjected to unnecessary shutdowns due to overpressure issues, helping to avoid disruptions and inefficiencies in your operations.

⏰ When Should You Inspect? ⏰

While each system is unique, a general guideline is to schedule maintenance annually or based on your specific process conditions and operational risk levels.

📌 Takeaway 📌

Routine PSV maintenance isn’t just good practice— it’s critical to ensuring your systems are safe, efficient, and compliant.
