Lifting and Handling

Actuators and valves with externally fitted components may be damaged when in transit/during handling or turning ready for welding onto the pipe work or manifold installation by incorrect lifting methods or inexperience. The most common damage caused by incorrectly slinging or lifting of the valves are as follows:

  • Compensators and pipe work
  • Visual Indicators
  • Valve body end connections (either BW or Flanged)
  • Gearbox casings (ball valves)
  • ROV receptacle
  • Spring outer casings fitting connections

In the case of damaged compensator or pipe work this will result in the oil draining from the valve actuator compensator system which will require, after the damaged components are replaced, to be filled and re-tested. BEL Valves offer experienced service technicians who have attended safe lifting courses in the UK to ensure the risk to personnel safety and potential damage is reduced to the minimum.Due to past experience of equipment being damaged during transportation when arriving at site BEL Valves offer commissioning spares to cover these possible incidents.

  • Assist project personnel during the site FAT to ensure the valves are functioned into the correct position to allow the system to be fully filled and closing the valves when required to carry out seat testing. All torque readings are recorded for future reference in the final service documentation which will be entered into the project documentation.
