Watching them install those bargain-bin valves on the steam main is giving me actual anxiety.

Bargain valves can handle steam pressure just as well as expensive ones.

My buddy's factory had a similar valve fail (it wasn't pretty).

Upgraded to a dual-safe valve and it held up.

Thermal cycling often undermines dual-safe valves unless monitoring is meticulously calibrated, from my observations.

Honestly, the real test isn't just pressure holding, it's how those valves handle thermal cycling over time. Tbh, most failures I've seen come from repeated expansion and contraction weakening seals. Ngl, a lot of specs don't account for rapid temperature changes in real world setups. People forget that a dual-safe design can still have a single point of failure if the monitoring system isn't calibrated right.

Oh man, I once saw a coolant line fail from exactly that kind of thermal stress. The rubber seals got brittle after a few hundred cycles and just gave out overnight. Really makes you question the whole 'set it and forget it' mentality with some of these components...
