A metering valve includes a valve body, a flow tube, an orifice plate, a central flow body, and a mover. The valve body has an inlet and an outlet. The flow tube is carried for axial movement in slidable and sealing engagement with the valve body at an inlet end and an outlet end. The orifice plate has an outlet. The central flow body is provided on an upstream end of the orifice plate and has an annular seal configured to seat into engagement with the outlet end of the flow tube when the flow tube is moved to a downstream position. The central flow body also includes a central, protruding flow diverter upstream and central of the annular seal. The mover is provided in the valve body and is configured to carry the flow tube for displacement of the output end toward and away from the central flow body.
