A forged steel globe valve is a type of valve used for controlling the flow of fluid in high-pressure systems. It is constructed from strong and durable forged steel, known for its durability and strength.

There are different variations of forged steel globe valves based on their characteristics and design. A full bore forged steel globe valve has a larger internal diameter, allowing for unimpeded flow of fluid. This type of valve is commonly used in pipeline systems where high flow rates are required. On the other hand, a reduced bore forged steel globe valve has a smaller internal diameter, creating a flow restriction and resulting in a pressure drop. It is typically used in applications where flow control is critical, such as process control systems.

Both full bore and reduced bore forged steel globe valves feature a movable disk or plug that controls the flow of fluid. When fully open, the disk is moved out of the way, allowing unimpeded flow, while in the closed position, the disk is lowered to block the flow path.

Forged steel globe valves are available with flanged ends and class ratings of 150, 300, 600, 1500, and 2500. The flanged end design allows for easy installation and removal by bolting the valve directly to a pipeline or component using a flange connection. This design is commonly used in industrial applications and provides a secure and leak-proof joint.

Additionally, some forged steel globe valves have a bolted bonnet construction, where the valve body and bonnet are joined together by bolts. This design provides a tight and secure seal, suitable for high-pressure applications. The bolted bonnet allows for easy maintenance and repair as the bonnet can be removed to access the valve's internal components. The valve is also equipped with a stem and a handwheel or actuator for controlling its position.

Another type of forged steel globe valve features a welded bonnet construction, where the bonnet is welded to the valve body. This construction provides a secure and leak-proof seal that can withstand high pressures and temperatures. The welded construction eliminates the need for gaskets or seals and offers increased durability and resistance to higher pressures and temperatures.

Forged steel globe valves are widely used in industries such as oil and gas, chemical processing, and power generation, where high-pressure and high-temperature applications are common. These valves are designed to provide reliable and durable performance in challenging environments, emphasizing safety and reliability.

In summary, forged steel globe valves with their various design options, class ratings, and bonnet constructions offer a versatile and efficient solution for flow control in high-pressure and high-temperature applications.
