Product Code : VF--BWCC-BW3-CU
1Double sealing design (bellows+packing) If the bellows fails, the valve stem packing will also avoid leakage and meet international sealing standards
2. No fluid loss, reduce energy loss and improve plant equipment safety.
3. Long service life, reduce replacement times and reduce operating costs.
4. Durable bellows seal design ensures zero leakage of the valve stem and provides maintenance free conditions.
5. PTFE soft sealing material is adopted for gas medium valve seat to improve the sealing performance of the valve.
6. High temperature resistance and 425. (: The valve seat is hard sealed with conical surface to achieve air tightness and zero leakage.

The welded bellows globe valve can be divided into straight through type, angle type and direct current type according to the structure. Welded bellows sealed globe valves are manufactured by introducing advanced technologies at home and abroad, adopting metal bellows sealing technology, high-performance elastic metal bellows, and have a long expansion fatigue life. The double bellows seal globe valve adopts the design of bellows seal, which completely eliminates the disadvantage of quick aging and leakage of ordinary valve stem packing seal. It not only improves the energy efficiency, increases the safety of production equipment, reduces maintenance costs and frequent maintenance, but also provides a clean and safe working environment
Welded bellows stop valve is applicable to flammable, explosive, highly toxic, toxic fluid, high-temperature heat transfer oil, liquid ammonia and other media with a nominal pressure of PN1. 6 - 4.0MPa and a working temperature of - 29~425 years. It is widely used in petrochemical industry, chemical fiber textile, plastic paper making, electric power steel, printing and dyeing rubber, natural gas and other gas systems. Its performance is safe and reliable, and it is widely used in industrial fluids such as ethylene glycol. Drive modes include manual, gear drive, electric, pneumatic, etc.
Packing of Standard Packing:
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’ is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
