When to apply a Zero emission valve

If you want to reduce your Scope 1, 2 and 3 GHG emissions to achieve your net-zero goals, the Mokveld Zero emission valve helps you with the following benefits.

GHG Scope 1: ZERO emission over the full lifetime

The Oil and Gas Methane Partnership (OGMP) document TGD2 shows that stem leakage of (control) valves can reach 180 tons CO2 equivalent per valve per year. Therefore elimination of the stem seal results in a significant reduction in Scope 1 emissions. These emissions shall be taken in account in the OGMP 2.0 framework for reporting. The Mokveld Zero emission valve reduces fugitive emissions to zero over the full lifecycle of the valve. Increase of leakage to atmosphere in time is history since the stem seal is fully eliminated, wear and tear has no effect on emissions.

For valves with pneumatic controllers the Environmental Protection Agency (EPA) reports more than 45 MMT CO2 equivalent emissions in the USA only. The OGMP document TGD1 indicates these emissions can reach 570 tons CO2 equivalent per pneumatic controller per year. For valves also equipped with a positioner this results in more than 1.100 tons CO2 equivalent per valve per year Scope 1 GHG emissions.

The Zero Emission Valve equipped with a PID controller and electronic pressure transmitters reduces this to Zero.

 Maintenance effort is reduced to a minimum by the proven axial flow design and even further reduced by the diagnostic capabilities of the state of the art servo drive technology in Mokveld’s Zero emission valve.

By preventing emission, this ground breaking valve has the lowest Scope 1 GHG contribution.

GHG Scope 2: extremely low power consumption

Full pressure balancing and a self-braking transmission reduces the power consumption to a minimum over the lifecycle of the valve reducing your Scope 2 emissions.

Power during stand-still can be cut, reducing overall consumption, as a result of the self-braking transmission. The power during movement is very low due to the pressure balancing of the internals and the elimination of the stem seal friction.

This results in a concept that can easily be powered by solar power, Uninterrupted Power Supplies (UPS) or No-Break systems but also by a battery or capacitor pack supplied with the valve

This extremely low power consumption of the Zero emission valve contributes towards achieving Scope 2 GHG goals.

GHG Scope 3: reduced energy consumption during production

Mokveld is well known for its tried-and-tested one-piece axial flow designs with its optimized flow path and full range of control trims. Our low weight and compact design reduces the environmental footprint already during the casting process. The streamlined flow path through the full-port expanded body prevents erosion and vibration and allows smaller valve sizes as a result of the inherent high capacity. These elements served as the basis for developing this new valve. The valve’s compact, lightweight design contributes towards achieving Scope 3 GHG goals - reduced value chain emissions.
