IV8F Series Ball Valve

Class 800, Regular/Full Port, Screwed, Socket,Butt Weld Floating Design

The 3-piece design is available for various schedule pipes. This type of construction is of swing-out design and easy inline maintenance. By removing body bolts & nuts the complete valve may be lifted out of the line or swing-out by keeping one bolt. The valve can easily swing out of the line providing complete entry and fast disassembly or maintenance. The swing away feature also maintains pipe alignment during inline maintenance. The 3-piece design offers the function of both valve as well as a union. It can be used in screw pipe ends, socket weld pipe ends, butt weld ends, extended butt weld pipe ends. These ball valves can be easily used for automation by using pneumatic and electric actuators.
