VALVE ACTUATION

Pipelines in the Oil, Gas and Petrochemical Industries are fitted with fail safe valve systems.

Air driven liquid pumps are used as a major part of this system, their job is to keep the valve open during use but in the event of a failure, to close the valve. This is done by using the pump to compress a large spring which keeps the valve open. In the case of an emergency, fire, loss of pressure in the pipeline or whatever other reason the power supply fails, the valve automatically closes.

Such systems can be found in

  • Offshore Oil Platforms
  • Oil Pipelines
  • Gas Pipelines
  • Chemical Pipelines
