Abstract
A poppet switch valve device includes a valve body, a first valve rod including a first valve member, a second valve rod including a second valve member, and a solenoid. When a jig engages with an engagement portion of the first valve rod and rotates the first valve rod so that an internally-threaded hole formed in the first valve rod engages with and moves forward and backward relative to an external thread formed on an outer circumferential surface of the second valve rod, the first valve rod is moved relative to the second valve rod in the axial direction. The poppet switch valve device further includes a restriction portion configured to restrict movement of the first valve rod relative to the second valve rod in the axial direction after the first valve rod is moved relative to the second valve rod in the axial direction using the jig.
