AST Solenoid Valves are important for the emergency shutdown protection for steam turbine. In normal operation, AST solenoid valve is powered off by electrified excitation, then seal off the oil discharge path on the AST pipes, setting up oil pressure in the lower cavity of actuator piston; when a parameter of turbine reaches a shutdown value, AST solenoid valve will lose power and start-up to release the safety oil. Other valves of turbine will be soon closed to shut down the whole unit.
Solenoid valve (20/AST) is a series of parallel arrangement, so there is a multiplicity of protective. At least one solenoid valve is opened in each channel to cause the machine to be shut down. At the same time it also improves the reliability of the four AST solenoid valves in any one of them being damaged or rejected.
