Series V817 Cryogenic Globe Valves
1-1/2" through 6" ANSI Class 150, 300, 600

The Series V817 control valve is designed specifically for use in 'cold box' applications. It is a single-seated, body-guided globe style with threaded seat ring. The extended neck allows the body to bonnet flange to be outside the cold box, simplifying maintenance and providing a low 'cool down weight'. This design is generally used in throttling and/or isolation control of cryogenic liquids and gases to -450°F (-268°C). For detailed specifications, please refer to the product bulletin V817-1.
