The application range of bellows sealed globe valves is wide, especially suitable for controlling high temperature, high pressure, and corrosive media.
Due to the good elasticity and pressure resistance of corrugated pipes, they can withstand large pressure differences.
Therefore, corrugated pipe sealed globe valves are widely used in industries such as petroleum, chemical, metallurgy, and power. In the petroleum industry, bellows sealed globe valves are often used for oil well testing and control during oil and gas extraction processes; In the chemical industry, bellows sealed globe valves are often used for controlling high temperature and high pressure chemical media; In the metallurgical industry, bellows sealed globe valves are often used for control in high-temperature and high-pressure steelmaking processes; In the power industry, bellows sealed globe valves are commonly used for control in high-temperature and high pressure boiler and turbine systems.
Product Features
1. Double layer corrugated pipe shaft seal, achieving zero valve leakage. Meanwhile, the graphite shaft seal is retained, providing a dual seal.
2. The super bellows can open the valve up to 10000 times, ensuring long-term operation.
3. Conical sealing design: Reliable sealing comes from the "scraping effect ". When the valve is closed, the conical sealing surface automatically scrapes off surface impurities, solving the problem of slag in steam pipelines The issue of damage to the metal sealing surface.
4. The globe valve with a large diameter larger than DN150 has a unique balanced valve plug design, ensuring the sealing performance and opening and closing force of the valve.
5. The valve stem is made of high-strength materials and has a lifting stem structure, which is convenient for valve operation and reduces the opening of the valve during opening, preventing the occurrence of water hammer in steam pipelines, effectively protecting the valve.
6. The independent valve stem threaded oil hole ensures effective lubrication of the valve outdoors or under high temperature conditions, ensuring that the valve can be manually opened and closed at any time.
7. The position indicator device can provide a visual understanding of the valve opening and also serve as a limit for handwheel rotation, protecting the bellows.
8. Provide different valve core designs for different purposes.
