Type 859 Standard Fin Globe Control Valve

The U.S. Type 859 globe control valve with cooling fin bonnet is used in extreme temperature applications. It is designed for modulating flow control in industrial applications at 400…700° F (204…371° C) at pressures less than 5000 psi (344 bar) (dependent on body and packing material). The added bonnet length and fins serve to reduce the heat in the parking area. This allows the
standard CV ring packing is to be used at higher process temperatures than could normally be tolerated with the standard valve.

APPLICATIONS

The Type 859 valve is widely used in high-temperature applications where steam, hot water, hot hydraulic oil, or other fluids or gases must be controlled precisely through 1/4 in. (6 mm), 1/2 in. (12 mm), 3/4 in. (19 mm) or 1 in. (25 mm) lines. Extended cooling fin valves are available for applications that exceed 700° F (371° C). During the selection process, consult the appropriate pressure and temperature rating literature of the body and packing materials. This information is available in the catalog or from the factory
