Stainless steel bellows globe valves are different from general globe valves. They have more reliable sealing performance due to their special corrugated pipe design, and are particularly suitable for pipelines with media such as steam, flammable, explosive, heat transfer oil, high-purity, toxic, etc. Therefore, they have been widely used in power plant, such as generator hydrogen system, cooling water pipelines, boiler steam pipelines, etc.

Application of WJ series Bellows Globe Valve

In addition to its excellent sealing performance, the WJ series bellows globe valves have many advantages that enable them to be widely used in power plants, such as:

- Strong corrosion resistance: Hydrogen has strong corrosiveness, so valves used in hydrogen pipelines need to have strong corrosion resistance. The corrugated pipe globe valve is made of high corrosion resistant materials such as stainless steel, which has good corrosion resistance performance.

- Good high-pressure performance: Hydrogen, steam, and other materials need to withstand high pressure during transportation. Bellows globe valves have good high-pressure performance, which can effectively ensure the safe operation of pipelines.

- Simple structure: The corrugated pipe globe valve has a simple structure, convenient maintenance and replacement, and can reduce pipeline maintenance and replacement costs.

How to Select A Suitable WJ Globe Valve for Your Generator?

When selecting the WJ series bellows globe valve, it is necessary to choose based on specific working conditions and pipeline parameters to ensure that the size, material, and performance of the valve meet the requirements, and ensure stable operation in high-pressure and high-temperature hydrogen environments. The main models of stop valves in this series include: WJ10F-1.6P, WJ15F-1.6P, WJ25F-1.6P, WJ50F-1.6P, WJ65F-1.6P.

Then how to choose the most suitable model among these globe valves? Yoyik has summarized several standards for your reference.

1. Valve material: The main body of the valve should be made of stainless steel or high-strength alloy materials to ensure the stability and corrosion resistance of the valve in high-pressure and high-temperature environments.

2. Corrugated pipe material: Corrugated pipes should be made of high-quality stainless steel or high-strength alloy materials to ensure the stability and reliability of valve sealing performance.

3. Size and pressure: Valves of appropriate size should be selected to match the on-site pipeline, and attention should be paid to whether the valve pressure meets the system pressure requirements.

4. Connection form: There are two types of bellows globe valves: butt welding connection and flange connection, and the connection method can be selected according to the usage requirements. Generally, flange connections are easier to connect and disassemble with pipelines,

5. Seismic performance: Valves should have strong seismic performance, which can ensure the stability and sealing performance of the valve in extreme situations such as earthquakes.
