The bellows stop valve, also known as the bellows seal globe valve, is designed to prevent any leakage of the valve stem by creating a metal barrier between the fluid medium and the atmosphere through automatic seam welding. This feature ensures complete sealing and makes it ideal for use in critical applications where even minor leaks can be dangerous or costly.
Compared to traditional globe valves, the bellows stop valve offers several advantages:
1. The U.S. Shield VTON imported bellows cut-off valve is built to last, significantly reducing maintenance needs and lowering operational costs. Its rugged bellows seal design ensures zero stem leakage, making it virtually maintenance-free.
2. The valve requires minimal opening and closing torque, which reduces operator effort and allows it to be operated with any type of actuator, enabling remote control.
3. It features an aesthetically pleasing design with a smooth flow channel that minimizes flow resistance, making it an energy-efficient and high-performance product.
4. The outer seal of the valve combines a bellows with graphite and stainless steel gaskets, ensuring a reliable and durable seal. These components can be replaced without long-term use, making it easy to maintain. In industrial settings, leakage from regular shut-off valves—especially when handling high-temperature, toxic, flammable, explosive, or radioactive media—can lead to environmental pollution and serious safety hazards. This valve provides a safe and stable solution, adhering strictly to advanced foreign standards in both design and manufacturing.
Stainless steel is an ideal material for producing bellows globe valves. The material used must have excellent plasticity, high elastic limit, tensile strength, and fatigue resistance, along with good weldability and stable elasticity. Austenitic stainless steels, such as 304 and 316L, are widely used due to these properties. While high pressure and pressure resistance are essential for valves and bellows, increasing the wall thickness can make the bellows stiffer and harder to operate. Instead of simply increasing thickness, manufacturers often add more layers to improve pressure resistance while reducing axial stiffness and the force required to open the valve.
Non-metallic corrosion-resistant materials, like fluoroplastic, offer excellent chemical resistance and are commonly used in anti-corrosion valves. PTFE corrugated pipe shut-off valves also have specific applications. However, their low strength and heat resistance limit their use to temperatures below 150°C. For more severe conditions, such as wet chlorine corrosion in the chlor-alkali industry, corrosion-resistant alloys are necessary.
