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.
Full Port YFMvalves are also available in stainless steel construction with bodies in EN 1.4408 / ASTM CF8M material.
Stainless steel valves are designed to maximize cleanliness and minimize areas where contamination could occur.
Lined Ball Valve Innovative Stem Sealing System
Stainless steel lever
Latching device minimizes possibility of accidental operation. Locking capability as standard. Made of stainless steel material
ideal for corrosive environments.
Innovative "pressure assisted" seal device provides the highest protection against fugitive emissions.
Anti blow-out integral ball and stem
Retains positive control and minimizes the danger of stem/ball failures due to liner damage at wear points.
At the body joint ensures that no parts of the lining can be crushed or deformed because of forces within the piping system.
Wide conical plastic connection
Designed to maintain total seal even under extreme thermal cycling.
Locked in fluoroplastic liner
Resists shrinkage and collapse, and permits vacuum applications.
Chemically modified PTFE seats
Provide greater pressure stability at higher temperatures than conventional PTFE.
