The pilot choke option: A. B. C. Is an orifice in the main pressure port of a two stage directional valve used to reduce flow to the system. Is a device that throttles the flow of pressurized fluid to linear actuators at the extreme ends of their travel. Is a check valve in the tank port that allows the use of the return line fluid as a pilot fluid. D. Is an adjustable meter-in or meter-out flow control used to adjust the main stage spool shifting speed. Premature AC solenoid failure can be caused by: A. B. C. Holding the valve fully shifted. De-energizing both coils simultaneously. Restricting spool movement. D. Using the low-shock shift option without installing restrictor plugs. Directional valve spools: A. B. C. D. Can require correct orientation for proper operation. Are all symmetrical. Cannot be interchanged. Should be interchanged to equalize wear.
