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.
Handle designed to be movable from the operating rod, which can beadjusted to lengthen the rod. Or handle can be fixed on the operating rodto prevent from falling off. Handle seat and locating plate adopt theintegral casting molding design, to get rid of traditional fission design, ismore convenient for installation and positioning adjustment.
Because of midsplit body, the force on seat can bebalanced on left and right side, to avoid uneven stress onbody and displacement of ball. The ball is contact with amuch smaller surface (seat rings). Consequently theoperating torque is much lower, reducing costs,spaceand weight saving.
Processing dovetail groove in metal body inwhich lining locked to resists shrinkage.collapse and blow-out,to strengthen theadhesion between body and liner,ensuringthe valve operated in the condition of slightnegative pressure and full vacuum.
Valve body takes design of stuffing box toreplace the fission structure to reduce theleakage point.
This new type ball valve with high platformfully compliance with ISO 5211 standardallowing use of standard mounting kits. Niceappearance and tight configuration.
