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.

Elektromechanisch gesteuertes Gasregelventil. The Young & Franklin 3010 Series sonic flow Gas Control Valves (GCVs) are electro-mechanically actuated (EMA) to provide excellent speed and valve position accuracy. This GCV electronically homes on power cycle and has a turndown ratio of ~100:1. The entire YF 3010 Series is certified for use in hazardous locations around the world and available in a range of sizes suitable for industrial or power turbines of any size. The valve body is coupled to an actuator assembly that contains a fail-safe spring to quickly close the valve, halting fuel flow in the event of a power failure or turbine trip condition. Shock absorbers protect the actuator drive mechanism and valve seats during rapid closing thus ensuring reliable operation, and independent position feedback can be obtained via 2 optional LVDTs. The complete system provides precise fuel flow delivery with reliable operation.
