Features & Benefits
Complete PFA Wetted Surface
All process-contact surfaces are PFA: body liner, ball encapsulation, seat, and stem washer provide universal chemical resistance.
Full Bore for Pigging
Full-bore ball matches pipe ID, allowing pigging operations and maintaining low pressure drop in transfer lines.
Locked Liner Design
Anti-rotation keys and mechanical locking prevent liner collapse under vacuum and rotation during cycling.
Anti-Static Continuity
SS316 core ball and stem with spring-loaded contact to body prevent static charge accumulation in flammable chemical service.
Wide Chemical Compatibility
PFA liner resists chlorine gas/liquid, concentrated sulphuric and hydrochloric acids, caustic soda, and organic solvents.
