Flap Actuator valves could also be called "2-way" valves. It is the balance
of spring pressure that normally seats the Actuator valve and air pressure
from the aft Control Valve, when commanded by the PIC that overcomes that
seating.
For retracting the Flap Up, a bungee cord also lends pulling force. Removal
of the aft cockpit flap control function requires normally tight Actuator
Valves. Perhaps those Actuator Valves could use some service as well.
Just saying,,,,,,

Mark, I've looked at your prior emails, but see no telephone number.
Going back to the original event, i.e. with the rear flap handle in the
neutral position, put the front handle down, air rushes out of the rear
flap handle/valve.
After studying the pneumatic diagram and Craig Payne's air system guide,
here's what I think initially was going on. Look at the attached diagram. I
think the diverter valve in the down air side is leaking, or jammed. That's
the only way, it would seem, that air can get into the aft flap valve.
Whaddaya think?
