The 733 has a similar if not identical Bleed system.

On the 733 it was common to see a Bleed trip off on a Bleeds off Take-Off.
If a reset was not successful, selecting the respective Engine Anti-ice on before attempting a second reset would usually allow it to reset (reopen).

The EAI is taken upstream, before the PRSOV, this allows the bleed air to flow, releaving an overpressure and avoiding an overpressure during the reset.
