Bellow Seal Globe Valve

JQF Valve factory manufactures durable bellow seal globe valves suitable for cutting or connecting pipeline media under various working conditions in industries such as petroleum, chemical, pharmaceutical, fertilizer, and power. The nominal pressure is PN1.6～PN4.0MPa, and the working temperature is -20℃～350℃. The double robust and durable bellows seal design (bellows + packing) ensures zero leakage of the valve stem. At our company, you can find a wide variety of valves, flanges, pipe fittings, pipes, and other industrial accessories. Our engineers work tirelessly to innovate and improve our products to better serve our customers.

3. Triple Stem Protection
The Bellow Seal Globe Valve undergoes enhanced heat treatment and surface hardening processes, resulting in outstanding corrosion and wear resistance.
4. Double-Insurance Bellows Seal
Right-angle flow channels combined with a patented bellows design ensure a safer seal.
5. Intuitive and Visual Opening Position
Clearly indicated valve stem position for intuitive operation.
6. Flexible Customization and Adaptability
Component materials, flange sizes, and interface specifications can be customized to meet specific operating conditions.

Features:

1. The Bellow Seal Globe Valve in stock features a rational structure and reliable sealing. The dual robust bellows seal design (bellows + packing) ensures zero leakage from the valve stem. No liquid loss enhances plant equipment safety and meets sealing standards.
2. The Bellow Seal Globe Valve's sealing surface is overlaid with Co-based hard alloy, providing excellent wear resistance, corrosion resistance, and abrasion resistance, resulting in a long service life. The lift position indicator is more intuitive.
3. The valve stem undergoes quenching and tempering and surface nitriding treatment, providing excellent corrosion resistance and friction reduction; the valve stem lift position indicator is more intuitive.
