What part of the valve does the bonnet contain?

The bonnet of a valve plays a crucial role in the overall functionality of the valve by containing the means for sealing the fluid. Essentially, the bonnet houses various components such as the packing and other sealing elements that prevent leaks of the fluid that the valve controls.

This sealing is vital as it ensures that the valve can operate effectively under pressure without allowing the fluid to escape, thereby maintaining system integrity. Proper sealing is critical in various applications to prevent environmental hazards and ensure safety within a working environment.

While other features like pressure gauge attachments, flow control valves, and liquid reservoirs can be associated with valves, they do not reside within the bonnet itself. The bonnet primarily focuses on the sealing aspects and securing the internal mechanisms, crucial for the proper functioning of the valve.
