Abstract
PURPOSE: To simplify the construction of a limit valve by moving a piston rod up and down directly by a pilot pressure thereby eliminating the need for electrical control.
CONSTITUTION: A stopper plate 38 of a pallet 37 comes against a piston rod 40 of an actuator 30 and stops. When an operator changes over the air connection after his work is over by stepping on a foot valve, compressed air from an external supply port 26 is supplied to an external inlet port 24 to push a valve body 22 of a shuttle valve to connect it with a pilot port 23 of a main valve to supply compressed air. Next, a main spool moves upward by the pressure to supply compressed of a main supply port 27 frm an external outlet port to the actuator 30 to lower the piston rod 40. Thus the need for electrical control is eliminated to simplify the construction of a limit valve.
