General Information Introduction The 1907 liquid fuel valve meters fuel to gas turbines under all operating conditions. The fuel valve is mechanically linked to and operated by a governor/actuator, which determines the amount of fuel flow required for any gas turbine mode of operation.
Manual 40131 1907 Liquid Fuel Valve with LVDT Position Feedback Chapter 2. Installation Installation Install the fuel valve square with the governor/actuator linkage to prevent binding. The actuator should use about two-thirds of the available output between minimum and maximum. The remainder of the actuator travel should be split between the maximum and minimum ends to assure positive position for shutdown and for maximum fuel.

Manual 40131 1907 Liquid Fuel Valve with LVDT Position Feedback Chapter 3. Principles of Operation General The fuel valve is used in conjunction with a governor/actuator. Fuel is metered to the turbine for starting, acceleration, steady-state operation, and deceleration. Fuel flow is controlled by the mechanical linkage from the governor/actuator.
1907 Liquid Fuel Valve with LVDT Position Feedback Manual 40131 Bypass Feature A constant pressure drop is maintained across the metering port to allow the port opening to accurately meter fuel flow. Inlet pressure (P ) is applied to one side of the bypass diaphragm and outlet pressure (P ) to the opposite side.
