ABSTRACT:
Disclosed is a slide valve for control of product flow through it in which the valve internals, an orifice plate and guide assembly, are maintained in position by a circumferentially extending attachment stub surrounding and welded to a circumferentially extending weld-on stub welded to the orifice plate, the circumferentially extending attachment stub being welded to an internal end of the support cone and to the weld-on stub whereby the internals may be released and removed through the bonnet area of the slide valve by cutting the weld between the attachment stub and the weld-on stub, and replaced through the bonnet area and rewelding the weld-on stub and the attachment stub with another fillet weld. This places the fillet weld under compression rather than under tension, and is much stronger than the tension fillet welds in previous embodiments of this slide valve. Also, the refractory material when used can be finished in the shop rather than on site.
