Anyone know what the advantage offerred by the new "fixed" type hydraulic pressure switch ?

Does it not give less control over things?

If you have a small hydraulic leak which allows the pressure to bleed off ho long before the pump cuts in to restore pressure?

Currently if you set the adjustable type to say 1500 psi and the pressure slowly drops off to say1200 psi the doors will not open as there is sufficient PSI to keep everthing shut tight.

How do the fixed pressure switches ehave in this instance and once gear is up and doors closed how much PSI is actually required to keep eveythinn that way?

I probably only have a limited understanding of the hydraulics and perhaps this is where my quetsions arise...


What say y'all

Gerard
