The valve disc inside the bellows gate valve is plug-shaped, and the sealing surface is usually of two types: flat surface and conical surface. The disc of the bellows gate valve moves in a straight line on the center line of the medium on the pipeline.

What Is The Function Of Bellows for Gate Valve?

The bellows can reduce the impact of back pressure fluctuations on the performance of the gate valve; in addition, the bellows can play an anti-erosion role for the main parts of the valve such as the torsion spring.

What Maintenance Is Required For Bellows Gate Valves?

Regular inspection and maintenance are essential to ensure the proper functioning of bellows gate valves. The bellow seal gate valve should be checked for signs of wear, corrosion, or damage that could affect the seal. Lubrication of moving parts and stem is also important to prevent friction-related issues.
