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.
