(OP)
Does exist a check valve type which keep the piggability (gel pig) of the line where it is installed? (could it be useful a flapper valve type?)
Thanks,

I personnaly wouldn't do it again. If I got pushed into it I'd run something like a turbo pig that can tolerate a lot more abuse (might take 50 psid to push the pig through the valve, but it can be done).

The swing checks can be mechanically held in the open position to assist in passing a big one when necessary, but sometimes you cannot avoid an occasional cutout when luck (and everything else) goes against you.
