In the fine control of steam turbines, the efficient operation of solenoid reversing valve is the cornerstone to ensure the overall system performance and safety. With its precise electrical interface and flexible control signal types, the solenoid valve J-110VDC-DN10-DOF/20D/2N provides strong technical support for the intelligent operation and maintenance of steam turbines.

The electromagnetic reversing valve J-110VDC-DN10-DOF/20D/2N is a solenoid valve powered by a DC 110 volt power supply. Its nominal diameter (DN) is 10 mm, indicating that it is suitable for handling relatively small flow rates. The valve has a dual electric control function, which means that it can be controlled by two independent electrical signals. The electrical interface of the electromagnetic reversing valve J-110VDC-DN10-DOF/20D/2N is designed for connection to a DC 110 volt power supply. It is equipped with a quick-connect electrical plug for easy on-site installation and maintenance.

The control signal of the electromagnetic reversing valve comes from the digital electro-hydraulic control system (DEH) of the steam turbine. The control signal type is mainly a DC pulse signal with a voltage level of 110VDC. When the DEH system issues an opening or closing command, the electromagnetic coil inside the solenoid valve will be energized or de-energized, generating a magnetic field change, which in turn drives the valve core to move and realizes the switching of the fluid path.

During the start-up process of the steam turbine, the electromagnetic reversing valve J-110VDC-DN10-DOF/20D/2N is used to control the flow direction of lubricating oil, sealing oil and cooling water to ensure that all parts of the steam turbine are fully lubricated and cooled. In the stop phase of the steam turbine, the solenoid valve is used to cut off the fuel supply and achieve safe shutdown.

The electromagnetic reversing valve is an important part of the steam turbine automation control and participates in the automatic start and stop, load tracking and emergency shutdown functions of the steam turbine. Especially in emergency situations, the solenoid valve can respond quickly, cut off the key fluid channel, avoid the expansion of accidents, and ensure the safety of equipment and personnel.

During regular maintenance and testing, the electromagnetic reversing valve is used to simulate the fluid flow under different working conditions and test the system response speed and reliability. For example, when calibrating the valve positioner, the solenoid valve can provide a stable control signal to ensure accurate feedback of the valve position.

The solenoid reversing valve J-110VDC-DN10-DOF/20D/2N plays an indispensable role in the field of steam turbine control with its unique electrical interface and control signal type. It not only ensures the safety and reliability of the steam turbine during startup, operation and shutdown, but also provides a solid foundation for automated control and safe response in emergency situations.
