Stop valve 25FJ-16PA2 Satpura power
Date:2025/3/11 8:27:39 Visits: Author:Dongfang YOYIK Engineering Co; Ltd,The stop valve 25FJ-16PA2 is a bellows-sealed valve designed for the hydrogen system of power plant generators. It is mainly used to control the flow, pressure regulation and safe shutoff of hydrogen medium. Its core function is to ensure the sealing and operating stability of the hydrogen cooling system. It is also suitable for high-temperature, high-pressure and corrosive media environments such as petroleum and chemical industries.
Key features and requirements:
1. Structural design
- The stainless steel sealing surface and nitrided valve stem are used to improve corrosion resistance and wear resistance to ensure long-term reliable operation.
- The bellows sealing structure achieves zero leakage, effectively prevents hydrogen leakage, reduces safety risks and medium loss.
2. Application scenarios
- Mainly used in the hydrogen cooling system of thermal power plant generators to control hydrogen on and off and pressure regulation to ensure safe and efficient operation of generator sets.
- It can be extended to high-pressure and corrosive medium pipelines in the chemical, petroleum and other industries, and the applicable pipe diameter is usually not more than 100mm.
3. Installation specifications
- The valve needs to be installed vertically to the horizontal plane of the pipeline to avoid medium backflow; before installation, impurities such as welding slag and rust in the pipeline must be thoroughly removed.
- The recommended connection method is argon arc welding or special sealing gaskets (made of stainless steel, polytetrafluoroethylene, etc.). It is strictly forbidden to use insulating materials for sealing.
4. Maintenance and safety
- Regularly check the status of the bellows and sealing components, and replace the worn parts in time; the operating environment must meet the explosion-proof requirements, and the operation must be performed by professional technicians.
- When purging the system, oil-free air or inert gas must be used, and the flow rate must not be less than 20m/s to ensure the cleanliness of the pipeline.
