Product Description

Wats valve high quality Angle Bellows Globe Valve adopts a 90-degree design, which allows the fluid to change direction at right angles and control the flow or cutoff of the fluid by rotating the valve stem. The metal bellows is used as the main sealing component inside the valve body, combined with traditional packing. The valve disc moves linearly along the center line of the fluid, and the bellows expands or contracts accordingly, isolating the fluid from the external environment and preventing leakage.

Performance Characteristics

The structure of Angle Bellows Globe Valve makes it particularly suitable for applications with high reliability requirements, such as systems handling toxic, flammable or corrosive media.

Advantages

1. The key component of Angle Bellows Globe Valve is the metal bellows. It connects the valve cover and the valve stem by automatic roll welding. The metal bellows ensures that the valve stem part is leak-free.

2. Thanks to the conical and streamlined design, the valve disc seals reliably and has a longer service life.

3. Double seal design (bellows + packing). The bellows and packing prevent leakage and provide excellent sealing effect.

4. Angle Bellows Globe Valve can directly lubricate the valve stem, nut and sleeve.

5. Ergonomic handwheel. Longer service life and easier operation.
