Products Description:
1. Two pieces full port standard lined ball valves offer high stability, rigidity and eliminating potential leak path.
2. Full port design minimizes pressure losses and increases flow capacities thus reducing energy and pumping costs.
3. Full bore design almost no fluid resistance, and good shut-off performance.
4. It features zero leakage, maintenance-free, one-piece stem and ball design, high sealing performance and can be used under full vacuum service.
5. Lower pressure drop and high flow characterized the efficiency of Youfumi lined ball valves.
6. It can work as on-off or control valve.
7. 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.
8. Lining material: PFA, FEP, GXPO etc.
9. Operation methods: manual, worm gear, electric, pneumatic and hydraulic actuator.
10. Youfumi lined ball valves are available as per the needs of applications in additional sizes and other than standard materials.
YFM dynamic body joint design retains pressure boundary during thermal cycles
The body assembly has metal-to-metal connection that offers resistance against forces that may be created in the pipework.This feature is designed to alleviate deformation and damage to the lining, even under pressure induced stresses. Also,the body joint sealing is provided with taper lining overlap, which is especially effective under high internal pressure and temperature variations.
