A bellows seal globe valve is a specific type of globe valve designed with a bellows structure to enhance its sealing capabilities. This valve consists of a globe-shaped body with a movable plug or disc inside that regulates the flow of fluids. What sets it apart is the bellows assembly, typically made of metal, surrounding the valve stem.

The bellows serve as a critical component for sealing, providing a barrier between the fluid within the valve and the external environment. It helps prevent leakage, especially in applications involving hazardous or volatile fluids, where maintaining a tight seal is crucial for safety and environmental protection.
