RE: External cavity relief
what applications may require DPE x DPE ?
RE: External cavity relief
It's really just pro/cons between the two and they're only really comparable if you maintain, monitor, and test them on some frequency. The DPE x DPE arrangement, if you properly maintain them properly, lets you know that a single seal has failed, hopefully some time before the other one does so you can address it before both seals are shot. You can also get SPE x DPE if you want preferential, dual sealing in one direction while having inherent cavity overpressure protection.
