Bolted Bonnet Gate Valve Design

Bolted Bonnet Gate Valve

Bolted bonnet gate valve is a type of industrial valve used in piping systems to control the flow of fluids. It consists of a gate or disc that moves up and down to regulate fluid flow through the valve body. The valve is typically operated manually or by a hydraulic or pneumatic power actuator.

This gate valve is so named because it has a bonnet bolted to the valve body. The bonnet is the valve’s top portion covering the stem, packing, and other internal components. The bonnet is bolted to the valve body to create a tight seal and prevent leaks.

This type of valve is commonly used in applications requiring tight shut-offs, such as high-pressure steam systems, oil and gas pipelines, and petrochemical plants. The bolted bonnet design allows for easy maintenance and repair of the valve, as the bonnet can be removed to access internal components.

Overall, this valve is a reliable and durable one that can withstand high pressure and temperature conditions, making it a popular choice for industrial applications.
