Abstract
A flow control valve has a fixed orifice adjacent to a movable orifice. The fixed orifice is secured to a cage that is in turn secured to a bonnet. This allows the fixed and movable disc to be simply installed and removed from the body through the bonnet. The stem assembly features a forked member for a strong grip of the movable disc. The design removes the need for precision machining bores in the body and facilitates assembly or removal of the valve internals.
