Butterfly valve actuator time

ENRG

Hello; just need approximations here. 16 inch buttterfly valve with separate environments on each side. side one: clear water at about 8psi; side two: air at about 33 psi; Consider both pneumatic and electric actuatiion under ideal conditions.What is the approximate fastest time to open and the fastest time to close? We are looking at quarter turn.
