Abstract:

In accordance with the present invention, there is provided a linear displacement control valve comprising a valve body having a valve bonnet cooperatively engage thereto. The body and the bonnet collectively accommodate a valve trim which comprises a flow control element and a complementary spindle. The spindle is preferably attached to a reciprocally movable valve stem of the control valve via a stem adaptor. The stem adaptor is adapted to allow for some measure of “float” between the spindle and the flow control element as may be needed to accommodate any misalignment therebetween. The spindle is uniquely configured such that when used in conjunction with the flow control element, the trim is capable of providing low end flow control at a higher level of accuracy and/or wider rangeability.
