The Type 884 extended bonnet globe control valve is available in varying lengths for 1/4″ through 1″ line sizes. It is specifically designed for control of extremely cold or hot fluids and gases. In cryogenic applications, the bonnet length serves to extend the packing area, as well as allow room for insulation around the body and bonnet.
The design also facilitates cold box mounting. A casing flange is available as an option if sealing to the cold box is required. Other models are available to facilitate removal of the inner valve and seat from outside the cold box (Type CBX). In hot applications, the extended bonnet allows the standard TFE packing to be isolated from high temperatures. The factory should be consulted when service temperature exceeds 800° F (426° C).
