Die Y&F 8580 Serie Gas Control Assemblies ermöglicht eine schnelle und zuverlässige Kontrolle des Gasbstroms zum Verbrennungssystem einer grossen Industrie- oder Nutzgasturbine. The Y&F 8580 Series Gas Control Valve Assemblies provide fast and reliable control of gas fuel flow to the combustion system of a large industrial or utility gas turbine. The two-way valves provide variable flow control in applications requiring highly linear critical gas flow relative to valve stroke. The hydraulic actuator assemblies provide safe turbine fuel shutoff and reliable valve positioning. Control valve positioning is affected through a triple coil, two-stage servo valve that recieves a +/- 8 mA command. Position feedback is measured using two LVDT’s. Y&F 8580 Series Valves utilize a common design for 1” to 10” line size applications. Line Size: 2" -- 3" -- 4" -- 6" -- 8" Flow Characteristics: 2"- 8" (Linear) Maximum Cg: 2" (1,200) -- 3" (2,900) -- 4" (4,300) -- 6" (6,600) -- 8" (13,000) Hydraulic Pressure: 1200 to 1700 psig Maximum Operating Pressure: 1700 psig Proof Pressure: 2800 psig Maximum Rod Seal Drain Pressure: 10 psig Maximum Return Pressure: 30 psig Trip Valve: Independent electric or hydraulic trip valve Trip Time: < 100 ms for up to 6” valve, < 200 ms for 8” or larger valve Trip Relay: Low Pressure (100 psi) -- High Pressure (1600 psi) -- Electric (125 VDC) Feedback: 0.7 to 3.5 Vrms LVDT feedback with 7.0 Vrms input RVDT feedback: Available for rotary valves; limit switch standard for aux/stop valves Servo Command: +/- 8 mA servo command; +/- 60 mA servo command options available Typical slew time: 0.7 +/- .03 second; 0.200 second slew time available for some models Failsafe: Close Overboard leakage: Zero leakage, as shipped Failure Mode: Spring type to drive valve to safe position with loss of signal (Fail Close) Component Certifications: Certified to North American and European standards for use in hazardous locations

Der Digital Motor Controller (DMC) akzeptiert eine Position oder dreifach redundante Geschwindigkeitsbefehle, um die gesamte Reihe von Y&F Elektromechanische Aktuatoren (EMA) zu betreiben. The Young & Franklin 1100D300 Series Digital Motor Controller (DMC) accepts a position or triple redundant velocity commands to run YF’s full suite of Electromechanically Actuated (EMA) products. With a peak rating of 3.5 kW, the 1100D300 DMC provides ample power while being precise enough to ensure accurate positioning. The dynamic response of the 1100D300 DMC can be uniquely tailored to fit customer needs, allowing for a drop in replacement of existing systems. The 1100D300 is certified to EN61800, guaranteeing excellent noise immunity, and incorporates a flexible control scheme including Enable, Reset and Trip functions. No user programming is required due to factory software configuration.
