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: When an operator makes a change over by stepping on a foot valve, compressed air from an external pilot supply port 25 is supplied to an external pilot port 21 to push a check valve body 20 against the force of a spring 22 to let the air flow into a pilot port 14 via a flow through port 23 to move a valve body 27 by a differential pressure against a spring 28 and the pressure from a supply port 23. Thus the compressed air is supplied from a flow out port 31 to an external stopper cylinder 41 to lower a piston rod 40 thereby simplifying the construction of a limit valve eliminating the need for electrical control.
