Plug Seal Adjustment
1. Prior to adjusting the seal assembly (key 12 and 13), align the plug (key 2) with an open inlet port and insert the
supplied adjustment tool. Once this tool has been secured to the seal adjuster (key 18), rotate this tool counter
clockwise until the scraper (key 10) touches the inside surface of the body (key 1). The resistance to rotate the
adjustment tool will increase once the scraper contacts the body. Remove the adjustment tool.
2. Rotate the plug (key 2) a few revolutions to check for binding or excessive turning torque. If the plug rotates
smoothly, then insert, secure, and rotate the adjustment tool counter clockwise to tighten the seal adjuster (key
18) to the appropriate torque value listed in table 7.
Note
Do not exceed the torque values listed in table 7. Exceeding these values may cause the valve to not function as intended.
