Abstract
In a valve used in a nuclear power plant, a valve body from which a valve stem projects upwards is connected with a valve drive device for driving the valve stem by a hollow cylinder which is provided concentrically with the valve stem. On the hollow cylinder, strain gauges are attached to detect both torque and thrust, thereby detecting load exactly.
