The AGV50 Fuel Metering Valve is intended to meter fuel for turbines in the horsepower range of approximately 5,000HP to 60,000HP. This intelligent fuel valve includes a built in venturi based flow meter providing a very accurate calculation of fuel flow.

By providing an internal mass flow calculation, the valve is able to insure accurate fuel flow even with changes in supply or back pressure or changes in ambient air temperature.

The main differences between the AGV 10 and AGV 50 are:

The physical size of the body is much larger on the AGV 50. The flange size is a standard 2”SAE series 61 for the AGV 50 and the flow measurement technique used in the AGV 50 is a venturi with DP transducer where it is a metering orifice on the AGV 10. The venturi reduces turbulence which can affect the accuracy of the measurement at higher flows. The electronic control housings are identical on both the AGV 10 and AGV 50.

Light off can be achieved at a pre-determined flow which is ideal for a specific turbine not by ramping start flow through a range as is the normal practice with position based fuel valves.

The flow through design allows the AGV 50 to tolerate extremely dirty gas. If the pilot stage gas is filtered, the valve can even tolerate a substantial amount of liquids in the gas.

By choosing the optional embedded acceleration control the valve can work with either PLC or even with older analog control systems such as the CCC Black Boxes.

 The AGV valves greatly simplify on-skid wiring and gas plumbing and the 24vdc 1 amp requirement will not require a new high voltage power supply.

 The Rs-485 serial port provides data via the modbus interface such as: Fuel Supply Presure, Differential Pressure, Engine Manifold Pressure , Measured Fuel Flow, and various other On Board information available for control and diagnostics.
