225. According to the illustration, what actuates the bellows «I» in the gland seal regulator
The bellows 'I' is actuated by gland seal steam pressure, as this regulator controls that pressure. The illustration shows passages from the gland seal steam manifold connected to the bellows chamber, confirming this actuation. Lubricating oil, throttle steam, and control air are not connected to the bellows.
