Applications:

Valves are mechanical devices that controls the flow and pressure within a system or process. They are essential components of a piping system that conveys liquids, gases, vapors, slurries etc..Different types of valves are available: gate, globe, plug, ball, butterfly, check, diaphragm, pinch, pressure relief, control valves etc. Each of these types has a number of models, each with different features and functional capabilities.

Regardless of type, all valves have the following basic parts: the body, bonnet, trim (internal elements), actuator, and packing.

The cover for the opening in the body is the bonnet, and it is the second most important boundary of a pressure valve. A bonnet acts as a cover on the valve body, is cast or forged of the same material as the body. It is commonly connected to the body by a threaded, bolted, or welded joint.
