A Bellow Seal Globe Valve is a specialized type of globe valve that incorporates a bellows seal mechanism to provide a secure and leak-proof connection between the valve stem and the valve body. This design is particularly crucial in applications where the containment of hazardous or corrosive fluids is essential, as it prevents any leakage that could lead to environmental or safety issues.
The bellows, which is a flexible, accordion-like structure, is a key component of this valve. It expands and contracts in response to the movement of the stem, allowing the valve to open or close while continuously maintaining a tight seal. This seal is critical as it ensures that the fluid within the valve remains contained, even under varying pressures and temperatures.
