The main responsibility of the OPC solenoid valve SV13-12V-O-0-00 is to achieve overspeed protection. It is extremely sensitive to overspeed signals and is controlled by the digital electro-hydraulic regulator (DEH) system. In the event of load shedding or overspeed in the turbine unit, the DEH will send a pulse signal lasting 3 seconds to the solenoid valve, triggering the solenoid valve to operate.

When the solenoid valve receives the pulse signal from the DEH, it will open quickly, thereby relieving the pressure in the OPC oil circuit. This action will cause the valve to close quickly, cutting off the steam supply to the turbine, thereby preventing the turbine from continuing to accelerate and achieving overspeed protection. Once the turbine speed returns to normal levels, the DEH will cut off the power supply to the solenoid valve, the solenoid valve closes, and the OPC oil pressure is re-established. At this time, the DEH will adjust the opening of the gas valve to match the load of the unit.

In the OPC system, two SV13-12V-O-0-00 solenoid valves are usually configured to form a double-layer protection mechanism. This design is to prevent a single solenoid valve from failing to operate, and ensure that when one of the solenoid valves fails, the other can immediately take over the protection task, avoiding safety hazards to the turbine due to failure of overspeed protection.

The OPC solenoid valve SV13-12V-O-0-00 has the following characteristics:

1. Quick response: It can act quickly after receiving the signal to ensure timely and effective overspeed protection.

2. High reliability: The precision manufacturing process is adopted to ensure that the solenoid valve can work reliably at critical moments.

3. Simple maintenance: The structure is compact and easy to install and maintain.

The OPC solenoid valve SV13-12V-O-0-00 is widely used in the overspeed protection system of various steam turbine units, especially in the power generation, petrochemical, steel and other industries, and its stability and reliability have been widely verified.

The OPC solenoid valve SV13-12V-O-0-00 is a key component in the turbine overspeed protection system. It ensures that the regulating valve can be quickly closed in an emergency to prevent the turbine from overspeeding by accurately controlling the oil circuit pressure. Its double protection design greatly improves the safety of the system and provides a solid safety guarantee for industrial production.
