 AST system is the automatic stop trip system in steam turbine control. In the AST solenoid valve, the control oil passes through an orifice inside the unloading valve and acts on the upper part of the cup-shaped slide valve of the unloading valve. The force of the control oil is combined with the spring force of the small spring inside the unloading valve to press the cup-shaped spool valve of the unloading valve on the valve seat, sealing the oil return channel at the bottom of the main valve engine cylinder.
