装型の弁駆動装置。 In a valve whose valve body moves to open and close as the valve stem moves in the axial direction, a cylinder is connected to the valve body, and two parts in the cylinder are separated by a piston fitted in the cylinder. One of the high-pressure chambers is connected to a high-pressure fluid source, and the other low-pressure chamber is provided with a spring that biases the piston in the opposite direction to the high-pressure fluid, and the piston is moved to an appropriate position within the low-pressure chamber. A valve drive device with an internal limit switch, which is equipped with a limit switch made of a pressure-sensitive rubber sensor whose electrical resistance changes when compressed by a pressure sensitive rubber sensor.
