  • EVO II-HT G
  • EVO II-HT L
  • EVO III
  • EVO Lite
  • Optiflow Electr.

Overview Fuel Controls

HEINZMANN fuel controls are based on electric motor, digital electronic and safety technologies and experience developed in the HEINZMANN Group since the 1980's and products feature many innovations not found in competitor products. These features deliver ease and flexibility of application, quality of control and reliability for customers.

EVOLUTION II-HT G Gas Fuel Control

The EVOLUTION II-HT G Gas Fuel Throttle Valve (EVO II-HT G) is a mechatronic assembly consisting of a valve, position servo and digital flow controller with dual redundant pressure instrumentation built in. Utilising high accuracy position encoders both position and feedback accuracy is to within 1 bit over 4096.

Technical data

  • Power supply: 24 VDC
  • Power supply voltage range: 18 ... 32 VDC
  • Power supply current range: 1 ... 6 A
  • Ambient temperature range: -20 ... +85 °C
  • High accuracy, flow fully compensated for fuel pressure and temperature, suitable for DLE systems
  • Absolute repeatability
  • Highly responsive and stable
  • Reliable, does not require any flow sensor, self-cleaning valve surfaces
  • User configurable and maintainable using free PC application
  • Network enabled for Profibus, DeviceNet, Modbus or Ethernet field busses
  • 24 VDC power source only required
  • Competitive for wide range of turbine sizes
  • Lifetime self-adjusting seals protect against leakage
  • Independently SIL rated and certified for use in hazardous areas (ATEX and CSA)

EVOLUTION II-HT L Liquid Fuel Control

The EVOLUTION II-HT L Liquid Fuel Throttle Valve (EVO II-HT L) is a mechatronic valve assembly similar in form and function to the EVOLUTION II-HT G Gas Fuel Throttle Valve but for liquid fuels. The description is the same as the EVO II-HT G gas fuel throttle except for the following features.

Technical data

  • Power supply: 24 VDC
  • Power supply voltage range: 18 ...32 VDC
  • Power supply current range: 1 ... 6 A
  • Ambient temperature range: -20 ... +85 °C
  • Integrated recycle regulator block ready to use
  • BSPP ports to accept standard compression fittings for pump, manifold and tank connections
  • ANSI class 600 pressure rating for pressure atomised burner systems
  • Cartridge type recycle regulator valve for easy inspection/replacement
  • Independently SIL rated and certified for use in hazardous areas (ATEX and CSA)

EVOLUTION III Gas Fuel Control

The Evolution III Fuel throttle valve is a mechatronic assembly consisting of a valve, position servo and digital flow controller with associated redundant pressure instrumentation. The big brother of the EVO II-HT G system. Offering up to 100 Nm of torque. Designed to operate large valves that require high break torque and high accuracy. Complete with the Heinzmann flow calculation and dual redundant pressure sensors built in.

Technical data

  • Power supply: 24 VDC
  • Power supply voltage range: 18 ... 32 VDC
  • Power supply current range: 1 ... 6 A
  • Ambient temperature range: -20 ... +85 °C
  • High accuracy, flow fully compensated for fuel pressure and temperature, suitable for DLE systems
  • Absolute repeatability
  • Highly responsive and stable
  • Reliable and tolerant to dirty fuel supplies, does not use flow sensor, self-cleaning valve
  • User configurable and maintainable using free PC application
  • Network enabled for Profibus, DeviceNet, Modbus or Ethernet field busses
  • 24 VDC power source only required
  • Competitive for wide range of turbine sizes
  • Lifetime self-adjusting seals protect against leakage
  • Certified for use in hazardous areas (ATEX)

EVOLUTION Lite Fuel Control

EVO Lite is a pure positioner using the same hardware but without the flow control algorithm. Designed to operate on 4 – 20 mA signal and return a similar feedback. It can be adapted for almost any rotary actuator application, from fuel valves, through to air and swashplate control.

Technical data

  • Power supply: 24 VDC
  • Power supply voltage range: 18 ... 32 VDC
  • Power supply current range: 1 ... 6 A
  • Ambient temperature range: -20 ... +85 °C
  • Force up to 350 Nm
  • Mounting options to suit most applications
  • Process feedback of position and force
  • Highly efficient gearhead optimises utilisation of electrical power

OPTIFLOW Electrial

Optiflow is a highly cost effective concept for liquid fuel systems. Providing a high-pressure positive displacement pump driven by electric motor, that can be varied by a control mechanism to give both pump and throttle function in one system. Accurate, very responsive and suitable for all black start applications. ATEX certified.

Technical data

  • Power supply: 24 VDC
  • Power supply voltage range: 18 ... 32 VDC
  • Power supply current range: 1 ... 6 A
  • Signal demand: 4 ... 20 mA scaled to heat, mass or volume
