product manual
Bellow seal globe valve is suitable for cutting or connecting the pipeline medium in various working conditions of petroleum, chemical, pharmaceutical, chemical fertilizer, power industry and other pipelines with nominal pressure PN1.6 ~ PN4.0MPa and working temperature -20 ℃ ~ 350 ℃.
Structure and Use
1. Reasonable product structure, reliable sealing performance, beautiful appearance;
2. Surfacing Co-based hard alloy on the sealing surface, wear-resistant, corrosion-resistant, good friction resistance and long service life;
3. Valve stem quenching and tempering and surface nitriding treatment have good anti-corrosion and anti-friction properties;
4. Double seal of right-angle German standard bellows globe valve, more reliable performance;
5. The valve stem lifting position indication is more intuitive;
6. The material of the parts, the size of the flange and the number of the butt welding can be reasonably selected according to the actual working conditions or user requirements to meet various engineering needs.
