するロジック弁。A stopper that can adjust the setting position of the valve opening of the poppet valve, which is pressed by a spring against the valve seat, is arranged so that it can come into contact with the back of the poppet valve, and the poppet valve can be adjusted to the set opening by controlling the pilot signal pressure to the back of the poppet valve. In the logic valve, the stopper has a piston at its tail end, and the piston contacts a hollow sleeve that can move forward and backward with an upper limit opening adjustment screw, thereby adjusting the upper limit of the valve opening by the stopper. On the other hand, the hollow sleeve has a piston-shaped head that can move forward and backward with the lower limit opening adjustment screw, and the tip can slide freely within the hollow part provided at the tail end of the stopper. The piston-shaped head of the rod engages with the hollow part of the tail end of the stopper, allowing the stopper to set the lower limit of the valve opening, and the piston at the tail end of the stopper. A logic valve characterized in that both the upper and lower limits of the valve opening can be adjusted by moving the stopper between the upper and lower limits by controlling the pilot signal pressure to the back of the logic valve.
