Neles™ Finetrol™ Eccentric Rotary Plug Valves

Valmet’s Neles™ eccentric rotary plug valves, including the Finetrol™ series FC and FG, are engineered for precise flow control in demanding industrial applications. These valves combine the benefits of rotary motion with the control accuracy of globe valves, offering a robust solution for handling liquids, gases, vapors, and slurries—even in harsh and dirty process conditions.

Key Features

• Eccentric plug design ensures smooth, stable control over the full 90° rotation.
• Q-Trim™ attenuator for noise reduction and anti-cavitation, self-flushing and suitable for impure fluids.
• Heavy-duty construction with anti-blowout shaft and fire-safe certification (API 607).
• Live-loaded rotary packing for long-lasting fugitive emission control (ISO 15848).
• Certified to SIL 3 for safety-critical applications (IEC 61508).
• Versatile mounting orientations and wide temperature range: –200 °C to +450 °C.

Performance Benefits

• Excellent control accuracy and wide rangeability.
• Low maintenance costs due to rugged design and easy seat removal.
• Reduced dynamic torque, improving actuator efficiency and valve responsiveness.
• Environmental compliance with low emissions and clean air certifications.

Technical Specifications

• Size range: DN 25–300 (1″–12″)
• Pressure ratings: PN 10–100 / ASME Class 150–600
• Face-to-face dimensions: IEC 60534-3-2 / ISA 75.08.02
• Tightness classes: ANSI/FCI 70-2 Class IV (metal seat) and Class VI (soft seat)

Applications

• Refining and petrochemicals
• Chemical processing
• Natural gas
• Fertilizer production
• Power generation

These valves are ideal for severe service conditions, including erosive, dirty, and high-pressure drop environments. Their balanced plug design and modular trim options make them a preferred choice for control applications where reliability, safety, and performance are critical.
