FCT Top Entry Ball Valve

FCT Top Entry Ball Valve

FCT Top Entry Ball Valve – Simplified Maintenance, Reliable Isolation

FCT top entry ball valves feature a one-piece forged or cast body with direct top access to the valve internals, allowing seat and seal replacement without valve removal. This design is ideal for critical pipeline applications where downtime and disassembly are costly.

They are commonly used in offshore platforms, refining units, chemical plants, and anywhere compact, high-integrity shut-off with easy maintenance is required.
