As a Body Bonnet Manufacturer, share with you.

Bonnets are other important components for the gate and globe type. By dismantling the bonnet, the maintenance staff has access to the internal mechanisms and can replace components like the seat, the stem, etc (trim).
Valve bonnets are available in many designs and models (the most typical are: bolted, round bolted, welded, pressure seal) and are manufactured in cast steel or forged steel (generally using the same material grade of the body).
The bonnet is connected with the body by a threaded, bolted, or welded joint connections – and different types of gaskets are used to ensure leak-free connections between the body and the bonnet.

Our company also has Body Bonnet on sale, welcome to contact us.
