The main door of imported 300,000 units is only available. Some data are called hydraulic pressure relief valve. When the main door is closed, the steam pressure at the shaft end is unloaded to reduce the friction of rotation and speed up the closing of the main door.

During reheated main valve operation, the mechanical trip valve F3DG5S2-062A-50-DFZK-V is used to reduce the steam pressure at the shaft end of the reheated main valve. When the reheat main valve is in the full open position and the steam pressure in the reheat main valve body is in the operating condition, there will be leakage through the small gap between the reheat main valve shaft and bushing. The pressure at the reheat main valve shaft end will be the same as the operating condition, and the other end of the reheat main valve shaft will be in the atmospheric pressure. The force will cause the shaft to move towards the low pressure side until it is in contact with the spherical gasket. When the spherical gasket contacts, the steam leakage at the low pressure end will be eliminated or minimized. The spherical gasket on the reheat main valve has the same function as the stem and bushing backseat in the reheat regulating valve, but its operation is somewhat different. The load on the spherical gasket produces a large amount of friction; therefore, before turning the reheat main valve shaft, the oil-operated shutoff valve opens to unload the steam pressure at the shaft end to reduce friction and allow the reheat main valve to rotate freely.
