OPC is the overspeed protection of steam turbine, which is realized by OPC solenoid valve. When the speed of the steam turbine reaches 103% of the rated speed, the OPC solenoid valve opens, and the OPC acts to close the high and medium pressure regulating valve and each extraction check valve.

When the direct-acting solenoid valve is energized, the solenoid generates electromagnetic force to lift the closing member from the valve seat, and the valve opens; when the power is off, the electromagnetic force disappears, and the spring presses the closing member on the valve seat and the valve closes. It can work normally under vacuum, negative pressure and zero pressure, but the diameter generally does not exceed 25mm.
