Pressure Regulator vs Secondary Safety Device: Safety Myths Busted

Quick answer

The pressure regulator controls cooking pressure during normal use; the secondary safety device is a backup that should only act if primary pressure control fails. They are not interchangeable, and replacing one does not fix a problem with the other.

Why the two parts get confused

Both sit on the lid, both are small, and both are sold as Prestige spare parts. That similarity leads to a common assumption: any small part on the lid can be swapped for another. In practice, each part has a defined role, and the pressure cooker is designed around that division of labor.

The confusion matters because a worn regulator can look like a safety problem, while a damaged safety device can be mistaken for a regulator that needs adjusting. Treating one as the other can leave the actual fault in place.

What the pressure regulator actually does

The pressure regulator is the part that manages pressure during everyday cooking. It is a normal-use component, so it sees repeated cycles and is the more likely of the two to need replacement over time. If your concern is how the cooker behaves during routine cooking, the regulator is the part to inspect first.

Prestige lists the Pressure Cooker Pressure Regulator as suitable for a long set of models, including 57050, 57054, 46770, 57058, 57052, 58959, 57067, 51273, 57057, 55159, 57051, 46414, 57053, and 57056. Model fit is the first thing to confirm before ordering.

What the secondary safety device actually does

The secondary safety device is a backup. Its job is to act as a secondary safety valve for pressure regulation, which means it is not meant to be the part that manages pressure in normal cooking. Because it is a backup, it should not be treated as a tuning or adjustment part.

Prestige lists the Pressure Cooker Secondary Safety Device as compatible with models 46414, 46770, and 57050. That is a much shorter compatibility list than the regulator's, so check your model number before assuming it fits.

The exception: when the model list is the deciding factor

If your cooker is not on a part's compatibility list, the honest answer is that the supplied information does not confirm a fit. Do not order on the assumption that small parts are universal. The catalog gives model numbers, not universal-fit claims, and that limitation is the deciding factor in those cases.

Myths and verdicts

• Myth: The regulator and secondary safety device are interchangeable: Verdict: False. The regulator manages pressure during normal cooking; the secondary safety device is a backup valve. Each has its own compatibility list, and the lists differ. Match the part to the job, not just to the lid.
• Myth: Replacing the secondary safety device will fix routine pressure problems: Verdict: Misleading. The safety device is a secondary valve, not the part that regulates pressure in everyday use. If routine pressure control is the issue, inspect the regulator first. Identify which part is responsible before buying a replacement.
• Myth: Any small Prestige lid part fits any Prestige cooker: Verdict: False. The regulator lists many models; the secondary safety device lists only 46414, 46770, and 57050. Fit depends on your model number. Check your model against the specific part's list.
• Myth: A backup safety device means the regulator matters less: Verdict: Backwards. The backup exists because the primary pressure control is expected to do the everyday work. Keep the regulator in good order rather than relying on the backup. Treat the regulator as the first line, not the fallback.

The two Prestige parts at a glance

• Pressure Cooker Pressure Regulator: Suitable for Prestige pressure cookers 57050, 57054, 46770, 57058, 57052, 58959, 57067, 51273, 57057, 55159, 57051, 46414, 57053, and 57056. A broad model list makes this the part to check first when routine pressure control is the concern.

  

• Pressure Cooker Secondary Safety Device: Compatible with Prestige pressure cooker models 46414, 46770, and 57050. The narrower list means you should verify your exact model before ordering this backup part.
