FCT Floating Ball Valve

FCT Floating Ball Valve

FCT Floating Ball Valve – Compact and Efficient Shut-Off

FCT floating ball valves feature a ball suspended between two soft seats, which uses upstream pressure to press the ball tightly against the downstream seat for sealing. Their simple construction, compact size, and tight shut-off capabilities make them ideal for low- and medium-pressure applications across a variety of industries.

They are commonly used in chemical plants, utility systems, HVAC, and general-purpose pipelines where reliability, ease of maintenance, and quick actuation are key.
