The bellows globe valve is a commonly used valve in pipeline systems, designed with a bellows structure that imparts greater flexibility to the valve.

1. Structural Features: The main characteristic of the bellows globe valve lies in its use of bellows as the sealing element. Bellows is a flexible metal tube formed by multiple layers of corrugations, offering high bending and flexing capabilities. This structural design allows the bellows globe valve to better accommodate the bending and expansion of pipelines during operation, thereby enhancing the valve's reliability and durability.

2. Sealing Performance: The bellows portion of the bellows globe valve serves as the sealing element, providing excellent sealing performance. Due to the flexible deformation capability of the bellows, it can better conform to the valve seat when the valve is closed, ensuring a tight seal and effectively preventing media leakage.

3. Application Range: This type of valve is suitable for general industrial pipelines, HVAC (Heating, Ventilation, and Air Conditioning) systems, water supply and drainage systems, and other fields. Due to the special structure of its bellows, the bellows globe valve is particularly well-suited for situations where consideration of pipeline bending and expansion is necessary.

4. Operation Method: Bellows globe valves are typically operated manually, electrically, or pneumatically. Manual operation is suitable for small-scale systems, while electric and pneumatic operation are more applicable to large-scale systems, enhancing convenience and automation in operation.

5. Advantages of Use: The bellows globe valve offers superior adaptability and sealing performance compared to traditional globe valves. Additionally, its simple structure and easy maintenance contribute to reduced operational costs.

In general, the bellows globe valve, with its distinctive bellows structure, is widely employed in pipeline systems, offering a more reliable and efficient valve solution for industrial and construction sectors.
