A fuel valve for use in regulating the pattern factor of a gas turbine has a highly accurate pressure balanced clevis valve assembly. The clevis valve is pivotally mounted inside the valve housing by a flexure pivot, and has a pair of legs at each side of a valve body that control flow through pairs of flow orifices. An armature mounts to the clevis valve, and when energized, an electromagnet inside the valve housing generates magnetic flux that moves the armature to pivot the clevis valve to open or closed the orifices. The clevis valve is inherently balanced and can meter fuel through multiple orifices simultaneously.
