The hydrocarbon market is experiencing an electrification and Mokveld is part of that with electric actuated valves.
At present, a vast amount of (control) valves in remote locations are actuated by natural gas and in view of sustainability, carbon footprint and environmental factors, this should be reconsidered. The actuator, positioner and control unit cause fugitive emissions to leak into the atmosphere. Not taking the stem seal in account, this could easily add up to 18.000 Nm3 year. What is even more worrying is that this relates to a Global Warming Potential of 1,000 tons of CO₂ equivalent per year.
In view of cost, efficiency and also carbon footprint, air supply is not the best alternative either, specifically in smaller locations. In these cases, an electric actuated control valve is a good alternative.
Where the availability of electric power cannot be guaranteed, low power electric actuated valves could be considered. Direct Current low power actuators may be connected to the UPS or no break of the plant. In case the power requirement is low enough, solar panel solutions with battery back-up assure the up-time of the valves.
Mokveld axial flow pressure balanced valves require very low forces to move and can be equipped with very low power electric actuators which also allow solar powered applications.
