Product description:
1. Youfumi fully lined plug valves are cavity-free. Due to the special body design, the liner is firmly locked.
2. Plug coating is extended over the shaft sealing.
3. The lining are moulded into dovetail recesses in the body to lock them in place to prevents liner collapse in vacuum conditions and blow out in high pressure conditions.
4. Two way cavity free designs prevent accumulation of particulate matter making it an ideal choice for slurry application.
5. There is ideal taper design for the plug and the body cavity. When it failures to seal as a result of worn in using process, the three adjusting bolts in the cover work for external adjustment of in-line seal, to assure a maximum sealing capability and an extended service life.
6. Top sealing components form the second sealing. When the sealing surface failures to work, it prevents medium leaking through the valve stem.
7. Disassemble the four bolts on the cover, all the parts in valve can be took out, and replace the parts directly without the need to remove valve from pipeline.
8. Lined three-way plug valve is the best choice for corrosive diverter valve application.
9. It can sustain any corrosive medium in addition to the? ? Molten alkali metals and fluorine elements? ? . It is ideal products used in chlor-alkali, industrial in organic chemicals, metal and mining, nitrogen and phosphatic fertilizers, petroleum refining, pharmaceutical etc.
10. Lining material: PFA, FEP, GXPO etc.
11. Operation methods: Manual, worm gear, electric, pneumatic and hydraulic actuator.
12. Youfumi lined plug valves are available as per the needs of applications in additional sizes and other than standard materials.
