Q & A
Neles? Finetrol? Eccentric Rotary Plug Valve Series FC and FG Q & A
+ What are Finetrol eccentric rotary plug valves used for?
They are designed for control of liquids, gases, vapors, and slurries, especially in demanding applications such as refining, petrochemicals, natural gas, fertilizers, and power plants.
+ What distinguishes the Finetrol plug design from other eccentric rotary plug valves?
The Finetrol plug is balanced and includes a “tail element” that brings flow forces closer to the stem centerline. This enables a full 90° rotation opening range (versus ~50-60° in many conventional designs), improving controllability especially at small openings.
+ What are the key safety and compliance certifications for these valves?
- Certified to SIL 3 (IEC 61508) for safety performance.
- Fire-safe design according to API 607, 6th edition.
- Live-loaded rotary packing for low fugitive emissions, compliant with ISO 15848-1 (Class BH with endurance class CC-3).
+ What tightness / seat leakage classes are possible?
The valves offer metal seating (tightness Class V) and soft seating (Class VI), based on ANSI/FCI 70-2 tightness standard.
+ What are the environmental / fugitive emissions features?
- Live-loaded rotary packing minimizes leakage.
- Low emissions according to ISO 15848, with high endurance (mechanical cycles).
