YF 8641 Series Integrated Natural Gas Fuel Control Valves
The Young & Franklin 8641 Series Integrated Gas Control Valve Assembly is a balanced double-poppet flow control valve. This stainless steel bodied valve features a Fail-in-Place, NACE IV compliant design. With a known Cv curve, the 8641 can be operated via closed-loop positioning by any modern turbine controller.
When coupled to the YF 1100D300 Series Digital Motor Controller, the 8641 is a retrofit replacement for the hydraulic actuator, butterfly and loader valves commonly found on Solar Centaur, Saturn, Taurus and Mars gas turbines. The 8641 regulates flows directly based on compressor discharge pressure and set-point signals.
