Accurate Set Pressure Verification for Industrial Safety
Pop-up testing—also known as set pressure testing or cracking pressure verification—is a specialized method used to confirm the exact pressure at which a valve opens to release excess pressure. This test is crucial in verifying that the valve responds reliably during real-world overpressure events.
Set Pressure Verification – Confirm the manufacturer-rated set pressure.
Gauge Installation – Attach a calibrated, high-precision pressure gauge.
Controlled Pressure Application – Apply air, nitrogen, or water until the valve activates.
Valve Operation Observation – Monitor for “pop” and ensure reseating behavior is within tolerance.
Result Documentation – Record data for audit, compliance, and maintenance planning.
Reliable. Precise. Customizable.
