Bellow Seal Globe Valve

Bellow Seal Globe Valve is a type of globe valve designed with a bellows seal that prevents leakage around the valve stem. Globe valves are used to control the flow of liquids, gases, or steam by regulating the opening and closing of the valve disc, and they are known for their ability to provide precise throttling control.

Chenyu provides high-quality Bellow Seal Globe Valves that are designed to meet international standards and deliver reliable performance in even the most challenging applications. With our advanced manufacturing techniques and attention to detail, we ensure the highest level of safety, durability, and performance for our customers.

Bellow Seal Globe Valve Applications

  • Petrochemical & Chemical Processing: Handling toxic, volatile, flammable, explosive, or expensive media (e.g., benzene, chlorine, vinyl chloride) where leakage is unacceptable.

  • Power Generation & Metallurgy: Providing reliable isolation in high-temperature steam systems, heat transfer fluid lines, and corrosive chemical feed lines.

  • Pharmaceutical & Fine Chemical Industries: Maintaining purity in sterile processes or inert gas systems by preventing atmospheric contamination or process media escape.

  • New Energy Sectors: Used in processes involving highly corrosive and hazardous chemicals, such as in polysilicon production for solar panels and lithium battery material manufacturing.

 

Main advantage of Bellow Seal Globe Valve

  1. Zero-Leakage Stem Sealing: The metal bellows assembly acts as a primary, hermetically sealed barrier between the stem and the atmosphere, completely eliminating fugitive emissions from the stem packing. This is the core safety and environmental advantage.

  2. Enhanced Safety & Environmental Compliance: They prevent the release of hazardous fluids, ensuring personnel safety and adherence to strict environmental regulations, thereby reducing operational risk and liability.

  3. Long Service Life & Low Maintenance: The bellows design absorbs stem movement stress, reducing wear on dynamic parts. This robust sealing mechanism significantly extends valve service intervals by eliminating the need for frequent packing adjustments or replacements.

  4. Broad Service Compatibility: The availability of various main materials (from WCB to Duplex Stainless Steel) allows selection for services ranging from general utilities to highly corrosive media. Combined with a wide pressure range (150LB~600LB) and multiple operation methods, they can be configured for diverse and demanding automated control systems.

  5. Proven Design & Quality Assurance: Manufactured and tested to major international standards (e.g., ASME, BS, API598), these valves ensure reliable performance, pressure integrity, and dimensional interchangeability in demanding high-pressure/temperature services.
