 Operation & Assembly

- Vertical orientation requirement of valves during operation, testing, and installation is prescribed to all gate valves.

 - All gate valve operators must be assembled in the upright position vertically above the valve’s centerline.

1.  Gearboxes, actuators and necessary adapters must conform to the valve’s ISO pad top works design
2.  Adapter plates and gears must be bolted to the valve top works plate using the correct bolt size, torque, and tightening pattern.
3. The stem must be protected at all times from unnecessary movement, stress, force or other potential damage while ensuring the stem remains centered in the yoke tube during installation
4. Automation mechanisms must be designed, assembled, and supported in a manner as to not exert
5. uneven or unbalanced forces on the valve assembly that could contribute to a side load condition.
