A pressure relief valve (PRV) or safety valve is the device that protects a pressure system from over-pressure — the last line of defence if something else fails. Because that role is critical, relief devices carry their own inspection and testing regime alongside the vessel or boiler they protect.
What's involved
- Regular external inspection and condition checks — commonly around yearly
- Periodic set-pressure (“pop”) testing to confirm the valve lifts at its set pressure
- Overhaul and bench testing on a longer cycle — often around every five years, depending on service
- A register, tagging and due-date tracking so nothing falls out of program
Who does the testing
Set-pressure testing and recertification of relief valves is carried out through accredited partners. Speqo manages the relief-device program — inspection, register, tagging and due dates — and coordinates the accredited valve testing as a single point of contact, so you get a complete, compliant result without juggling providers.

Common questions
- How often do relief valves need testing?
- Relief valves commonly get an external check around yearly, with set-pressure testing and a longer-cycle overhaul (often around every five years) depending on service. The exact cadence is set by your inspection program and the equipment.
- Does Speqo test relief valves?
- Speqo manages the relief-device program and coordinates set-pressure testing and recertification through accredited partners as a single point of contact.
