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.
Youfumi Lined Ball Valve Advantages:
Lower Torque - Smaller Actuators
Lower torque:smaller actuators, reduced costs, space and weight saving
Fully compliant with ISO 5211 allowing use of standardized mounting kits
Allows installation in space restricted areas in parallel piping systems
All wetted components
Are fully lined with permeation resistant PFA material as a barrier to corrosion.PVDF and Anti-static PFA also available
Body and bonnet adopts socket structure which increase the sealing performance;
Dovetail design in body and bonnet can prevent lined material fall off under pressure and can suit for vacuum service;
General lined ball valve seat, Integral Structure, No self-compansate design, Shorter Lifespan;
Self-compansate Seat, Convex Sealing design can sweep up the ball surface and then decrease the abrasion between ball and seat ;
U- shaped groove gurantee better sealing performance
