In hydrogen-cooled generator sets, hydrogen not only serves as a cooling medium, but also participates in the energy conversion process. In this process, the hydrogen globe valve 25FJ-1.6P plays an extremely critical role. It is an important component to ensure the safe and efficient operation of the generator.

Since hydrogen is a flammable and explosive gas, its management inside the generator must be extremely strict. As a key control point in the hydrogen pipeline, the 25FJ-1.6P stop valve is responsible for quickly cutting off the hydrogen supply in an emergency to prevent hydrogen leakage from causing fire or explosion accidents. It is the first line of defense to ensure the safe production of power plants.

The valve ensures the stability of the pressure of the hydrogen circulation system inside the generator by accurately controlling the flow of hydrogen, which is crucial to maintaining the normal operating temperature and efficiency of the generator. Accurate flow regulation capability helps to improve energy utilization efficiency and reduce energy waste.

In a long-term operating environment, the hydrogen stop valve needs to withstand high temperature, high pressure and the corrosiveness of hydrogen. The 25FJ-1.6P valve body and valve cover are made of cast stainless steel, which is based on strict requirements for the chemical stability and mechanical properties of the material. The selection of stainless steel material not only ensures the corrosion resistance of the valve, but also ensures the mechanical strength under high temperature and high pressure conditions, extending the service life.

The 25FJ-1.6P stop valve adopts advanced sealing technology, such as bellows sealing design, which can effectively prevent hydrogen leakage and maintain good sealing performance even under frequent switching or long-term pressure. The flexibility and durability of the bellows ensure the tightness of the valve during opening and closing, improving safety.
