A controlled piston () having a first end () mounted in a controlled piston sleeve () and a spool () movably mounted in a spool sleeve (), a first fluid passage () from the spool () to the controlled piston first end (), the position of the spool () affecting a position of the controlled piston (), an FFV () in an FFV sleeve () in the first fluid passage () having a first end section (), a second end section () and a central section () having a third diameter less than the diameters of the first and second sections, the FFV () being shiftable between a first position blocking the first fluid passage () and a second position allowing fluid flow past the central section () to the controlled piston (), and a second fluid passage () from the spool () to the FFV first end section (). Shifting the spool () to a failsafe position shifts the FFV () to the first position to fix the controlled piston () in place.
