Die Y&F 8641 Serie Integriertes Erdgas-Kraftstoffregelventil ist ein ausbalanciertes Doppelkolbenventil für die Gasturbinenkraftstoff Steuerung. The Y&F 8641 Series Integrated Natural Gas Fuel Control Valve Assembly is a balanced double-poppet flow control valve for gas turbine fuel control. With a known Cv curve, it can be operated via closed-loop position control by any modern turbine controller. Additionally, with a specially programmed Y&F 1100 Series Motor Controller, the 8641 is a retrofit replacement for the Y&F 7-5078 Hydraulic Actuator, loader and butterfly valve fuel control system on several Solar gas turbines (including Centaur, Taurus, and Mars). In this application there is no need to upgrade turbine controls; the Y&F system regulates flow based directly on the Compressor DIscharge Pressure and Setpoint signals. Power: 120 Volt DC Nominal (80-180 Volt DC Range). Also operates on AC Motor position: 4-20 mA command Minimum/Maximum pressure: 0-435 psi(g) Minimum/Maximum fuel temp: -40°C to +150°C (-40 to +302°F) Rated flow: 6000 pph Valve body material: Stainless Steel Compliance: NACE IV Slew Rate: < 100 Milliseconds Full Stroke Response time: < 20 Milliseconds Options: RF 600# ANSI Flanges, 24VDC Nominal, (18 - 30 Volt DC Range), also operates on AC Options 2: NACE available Ratings: CE (PED, ATEX: ZONE 1) NA (Class 1, Div 1) Certifications: UL / CE / CSA / ATEX / PED / MD / IP-65

Die EIGV-Aktuatoren der Serie 8650 von Young & Franklin sind so gebaut, dass sie den Anforderungen von Betriebsumgebungen von grossen schwere Turbinen standhalten. The Young & Franklin 8650 Series EIGV Actuators are built to withstand the rigors of large frame turbine operating environments. These electric actuators are an upgrade from hydraulic air inlet controls, providing more reliability and better overall turbine performance. The EIGV Actuators are available with forces up to 30,000 lbf. and various stroke lengths. The 8650 Series features a sealed gear-train lubrication system, is self-contained and requires minimal maintenance. The entire assembly has been tested to over 20 years at temperature and load. Peak Force: Up to 30,000 lbf (133,400 N) Total Stroke: 4 in (101.6 mm) Slew Rate: Up to 0.60 in/s (15 mm/s) Fail‐Safe Mode: N/A Mounting Type: Bolted or Welded Operating Temperature Range: -40° to +266°F (‐40° to +130°C) Command: 4-20 mA Position, -8 to +8 mA Triple Redundant Velocity Ingress Protection: Available in IP54 and IP65 Mean Time Between Service: 96,000 Hours Maintenance Interval: 8 years (Gear‐train oil change only) LVDT Wiring: 6.56 ft (2 m) Flying Lead or MIL Connector Motor Wiring: 32.8 ft (10 m) Jacketed Cable Service Life: 20 Years Environmental: MIL-STD-810 - Shock and Vibration Certifications: Class 1 Div 2, Group B, C & D, T3 -- Ex db ib IIB+H2 T3 Gb
