<p>A slide valve (10) for control of product flow in which the valve internals are maintained in position by a stub (26) welded to an orifice plate (22) which in turn is welded to an internal end of a support cone (18). The valve internals, a guide assembly (30), and the orifice plate (22) may be released and removed through a bonnet area (46) of the slide valve (10) by cutting the weld between the stub (26) and support cone (18), and replaced through the bonnet area (46) and rewelding the remaining portions of the stub (26) to the support cone (18).</p> |
