The stop valve is suitable for the hydrogen cooling system of large steam turbine generators. The hydrogen leakage of the hydrogen system is an important indicator for assessing the installation quality of the unit. The bellows-type sealing valve design of the stop valve can ensure zero leakage of the valve stem seal and improve the installation quality of the generator hydrogen system. |
