Válvula de portão de caposta parafusada are a type of gate valve distinguished by their bonnet, which is secured to the valve body through a series of bolts. This design allows for easy maintenance and replacement of the valve's internal components, as the bonnet can be removed without disturbing the pipeline system.

These valves are primarily used for the on/off control of fluid flow within pipelines. They operate by utilizing a sliding gate mechanism, which when lifted, allows fluid to pass through the valve, and when lowered, provides a tight seal against the valve body, effectively stopping the flow.
