A flow control valve has a housing having a fluid inlet at one fitting end and fluid outlet at another fitting end, and a control body supported within the housing by support structure bridging between the control body and the housing such that for flow of fluid through the valve from the inlet to the outlet is along fluid paths symmetric with respect to an axis of the control body, the control body and support structure being streamlined so as not to interfere substantially with flow. At least one valve member is carried by the control body in an orientation for being shifted by driven movement along the axis relatively toward and away from the fitting end for control of fluid passing through the fitting end in response to an actuator within the control body. At least one port extends through the support structure for communicating with the actuator and providing for control of the actuator. |
