About Bellow Seal Globe Valve:
A bellow seal globe valve is a type of valve designed to provide a hermetic seal to prevent any leakage of the fluid being controlled. This valve is particularly useful in applications where the fluid is hazardous, toxic, or environmentally sensitive. The key feature of a bellow seal globe valve is its metallic bellows, which provides a superior seal compared to conventional packing, ensuring zero leakage and enhanced operational safety. These valves are commonly used in industries that handle dangerous or valuable fluids, such as chemical processing, pharmaceuticals, and nuclear power.
The valve’s high-performance sealing capability is facilitated by a number of essential design elements. To survive challenging operating circumstances, the primary body of the valve is usually built from sturdy materials like carbon steel, stainless steel, or other high-performance alloys. To regulate flow and pressure, a disc (or plug) that travels perpendicular to the fluid flow is housed inside the valve body. To guarantee a tight closure, the seat—where the disc makes contact to establish a seal—is precisely machined. This valve stands out due to its metallic bellows assembly. The bellows, which are typically constructed of stainless steel, are welded to the bonnet and stem to provide a robust and flexible barrier that keeps the fluid away from the stem.
Working Principle:
The disc’s movement and the bellows’ flexibility are key components of a bellow seal globe valve’s operation. The disk presses on the seat of the valve when it is closed, preventing fluid passage. When the handwheel or actuator is spun, the stem and attached disc are raised, enabling fluid to pass through the valve body and opening the valve.
The metallic bellows expand and contract with the movement of the disc, preserving a hermetic seal around the stem. No fluid escapes along the stem thanks to this smooth movement that doesn’t compromise the seal’s integrity. Because of the bellows’ flexibility, the valve may move with the stem while still providing a leak-proof barrier, which makes it perfect for applications where tight sealing. The fluid flow is stopped when the valve closes again and the stem lowers the disc back onto the seat. Throughout this process, the bellows compress but maintain their tight seal to stop any possible leaks. Bellow Seal Globe Valve Manufacturers in India can handle hazardous, poisonous, or high-purity fluids without sacrificing performance or safety thanks to their dependable sealing mechanism.
