Young & Franklin - Industrial Turbine Control Valves and Actuators

Young & Franklin is the premier design and manufacturing company for industrial gas turbine (IGT) fuel control. In addition, our engineers are tackling the most challenging applications in steam turbine control. Y&F develops standard component products as well as complete engineered solutions for OEM and overhaul markets.

Young & Franklin delivers control solutions based on four actuation technology platforms with distinct benefits: hydraulic, electromechanical, electrohydrostatic and voice coil.

HYDRAULIC ACTUATION

For over 50 years customers like GE Energy, Solar Turbines and Pratt & Whitney have relied on Young & Franklin's hydraulic expertise to control their turbines. Our robust actuators provide the basis for high force, fail-safe, reliable hydraulic control systems. More information about our hydraulic capabilities can be found at the end of this document. Products in this category include:

• 8577 IGCC Valves - for up to 16in line sizes - patented high torque actuation guarantees smooth closing for syngas processing - read about our IGCC experience online (see links below)
• 8580 Gas Fuel Valve Assemblies - for 1in to 10in line sizes, natural gas or syngas - offerings include electric or hydraulic trip relays
• 9200 Isolation Valves - single stage, solenoid operated, pilot controlled - drop-in replacement for 1in to 3in line sizes - closes in <100ms and has a Cv of 80 - double block and bleed system also available
• 8277 Inlet Guide Vane Actuators - for large turbines - 1,200psi to 1,700psi hydraulic pressure

ELECTROMECHANICAL ACTUATION (EMA)

Young & Franklin offers electromechanical actuation (EMA) for your electric fail-safe fuel control applications. Our patented compact, linear EMAs are the basis for a complete shipset of electric IGT controls. Some products in this category include:

• 3000/3001 Series EMA Actuators - can be flange or clevis mounted on your valve in hazardous / high-temperature locations
• 3030 Series EMA Stop / Ratio Control Valves - servo control over 0° to 90° - rotary actuation for 1in to 4in valve sizes
• 3010 Series EMA Gas Fuel Control Valves – 1in, 2in and 3in with balanced valve design, spring closure for added safety and reliability

ELECTROHYDROSTATIC ACTUATION (EHA)

If your application demands high-force, compact, electric actuation for turbine fuel and steam control, consider electrohydrostatic actuation (EHA). This technology provides an electric solution in applications where high force requirements dictate the use of hydraulic power. Young & Franklin's patents-pending electrohydrostatic actuators and electrohydrostatic actuators with failsafe systems combine the accuracy of electronic control with the high-force capability of hydraulics in a compact package. Some products in this category include:

• 8613 EHA IGV - compact package with failsafe accumulator and electronic thrusters
• 8614 Self-Contained Steam Valve and Actuator Assembly - for energy-saving on / off valve control in heavy-duty steam applications

VOICE COIL ACTUATION

For your low force, high-precision actuation applications consider a Young & Franklin voice coil actuated valve. Our patent-pending direct-acting heat dissipating voice coil activated valves have on-board integrated electronics that communicate with the provided controller package to deliver precision and reliability with no contact between moving parts. Some products in this category include:

• 7-2000 Low Pressure Servo Valve - for use with your lube oil pressure, the Y&F 7-2000 offers low-pressure (12psi to 700psi) servo control
• 7-2010 Electronic Actuator - this model is versatile for linkage actuation, gas turbine fuel valve control, or anything requiring pushing / pulling actuation
• 7-5079 Electronically Controlled Hydraulic Servo Actuator- can be used for your small turbine IGV actuation, bleed valve control and natural gas fuel control
