Three-Way Valve Refurbishment

Three-Way Valves are two-position valves designed to divert flow from one pipeline to another.

Flat seating surfaces combined with flexibility between the disc and stem provide a self aligning tight seal. Welded end connections are extended at least one pipe diameter away from the valve body to minimize the possibility of distortion during field welding.

When ordering refurbishment services be sure to give all the data on the valve reference plate, the number of the sectional illustration, and piece list forming part of this bulletin.  Also, the name and number of the parts required as numbered and described.

Key Three-Way Valve parts inspected to original specifications include:

1. Body integrity
2. Disc
3. Disc seat
4. Body seat
5. Bonnet
