ABSTRACT:
Disclosed is a valve in which the valve internals, the valve seat, guides and slide valve are maintained in position solely by a clamping action of a quick make-up cylinder having an inlet flow passage into the valve. The valve is particularly suited for small valves as no screws or other fasteners are used to maintain the valve internals in position. Advantageously, the guides and slides are maintained out of the flow path, and the valve internals, including the cylinder, are readily removable through the bonnet area.
