I assumed wrongly that the door was staying wide
open. ( I reread the previous mail) However the sequence valve
operates through the movement of the plunger and there needs to be enough
movement on the plunger to fully open the valve without the gear trying to
force it off its mounting when fully open. In other words there should be a
small amount of free movement when the gear is fully retracted and the
valve is fully open. That is what the adjusting screw is for. It
takes a lot of fiddling to get the adjustment but it can be done. I did it with
all pressure off, lifted the nose gear up and put a piece of wood up from the
floor to hold it in position.
Before you spring for the cost of a new valve get
whoever replaced your seals to check the action of the valve. There could
be a piece of shredded "O" ring lurking about partially blocking a port.
However having read all the the thread I rather end to think it is the
adjustment of the door.
No I have not replaced a sequence valve yet.
Unless it has physical internal damage there is really nothing to go wrong apart
from the seals.
