This one was an exact replacement for an original one installed in the water feed line to a pair of boilers ahead of the prv. The original failed to allow water into the system after only one heating season. The new corrected the issue - so far.

Yes, because it did what it was supposed to.
It was use in a boiler feed line to stop backflow.
