摘要: A measurement method for a steam valve according to at least one embodiment of the present disclosure, includes: a step of measuring acceleration of a valve stem when a slave valve is opened by driving the valve stem with an actuator from a fully closed state of a master valve and the slave valve; a step of detecting a timing at which the slave valve is fully opened, based on the measured acceleration of the valve stem; and a step of calculating an amount of movement of the valve stem from a reference position to a position where the slave valve is fully opened.
