A valve bonnet acts as a protective cover for the valve body. It is securely attached by threading, bolting, or welding.
During assembly, the internal parts like the stem and disk are placed inside, and the bonnet is installed to seal and secure them in place.
The drop-forging process creates a dense, durable component that withstands high pressure and stress.
