SLIDE VALVE WITH WELDED INTERNALS

摘要

A slide valve for control of product flow through it in which the valve internals are maintained in position by a stub welded to the orifice plate which in turn is welded to an internal end of the support cone and may be released and removed through the bonnet area of the slide valve by cutting the weld between the stub and support cone, and replaced through the bonnet area and rewelding the remaining portions of the stub to the support cone.
