    Abstract: Disclosed is a control slide valve for control of product flow through it in which the valve internals are maintained in position by the clamping action of a split clamp and may be released and removed and replaced through the bonnet quickly and easily by release and reclamping the split clamp rather than by utilizing bolts which often gall, break, and are difficult to remove and replace.
