Flange Ball Valve
The flanged Ball Valve Is A Quarter-turn (90°) Rotational Motion Valve That Uses A Perforated, Pivoting Ball To Control Fluid Flow. It Is Designed With Flanged End Connections According To International Standards, Offering Reliable Shut-off And Easy Installation In Industrial Piping Systems.
Key Components & Construction
Component Material Options Function
Body Cast Iron, WCB (carbon Steel), CF8 (304 SS), CF8M (316 SS) Pressure Containment, Pipeline Connection
Ball Chrome-plated Brass / Stainless Steel (304/316) Rotating Element That Opens/closes Flow
Seat PTFE, RTFE, PEEK, Nylon, Devlon Leak-tight Seal Around The Ball
Stem Stainless Steel (316/304) Transfers Torque From Handle/actuator To Ball
Stem Seal PTFE + O-ring (Viton/FKM/EPDM) Prevents Fugitive Emissions
Flange Gasket Surface Raised Face (RF), Flat Face (FF), Or RTJ Sealing For Flange Bolting
Blow-out Proof Stem Anti-static Device (standard On Quality Valves) Prevents Stem Ejection Under Pressure
Floating Ball Design (standard For ≤10" / ≤Class 300): The Ball Is Not Fixed; Line Pressure Pushes It Against The Downstream Seat For Sealing.
Trunnion Mounted Ball Design (for Large Sizes ≥12" Or High Pressure): The Ball Is Fixed With Top And Bottom Stems, Reducing Torque And Wear. Ideal For Class 600+.
