REGULATING MEMBER POSITION ADJUSTING DEVICE FOR HYDRAULIC CONTROL VALVE

PROBLEM TO BE SOLVED: To provide a regulating member position adjusting device for a hydraulic control valve enabling simple and accurate position adjustment of a regulating member, as well as being applicable to any regulating member of various size. SOLUTION: The position adjusting device is provided with a plate 1 having an opening 1A, a scale 2 with its one end to be fixed to this plate 1, and a position controlling body 4 installed on the other end of the scale 2. Thus the position controlling body 4 is placed on a location separated from the end face of the plate 1 by a certain distance to come into contact with the plate 1 with the end face of the valve body 10, extensionally install the scale 2 along the axial direction of the regulating member 11, and insert an adjusting wrench 7 into a wrench through hole 6A, allowing the regulating member 11 to rotatably be moved until it comes into contact with the position controlling body 4.
