Mokveld Valves, a Dutch global leader in the development and production of high-quality control and safety valves, has announced that Gasunie has decided to enter a long-term frame agreement with Mokveld for its Zero emission valves.
A formal market consultation by Gasunie confirmed the Mokveld concept without a dynamic seal to the atmosphere is unique and contributes to the reduction of GHG scope 1, 2, and 3 emissions. Gasunie anticipates on upcoming EU legislation regarding further emission reduction and leak detection and repair (LDAR) requirements.
The Mokveld Zero emission valve fits in perfectly with Gasunie’s objectives to reduce GHG scope 1 reduction. The omission of the dynamic seal assures zero emission over the lifetime, where conventional control valves tend to show ‘wear and tear’ of the stem packing resulting in an increase of emissions over the life time. In addition, the lack of a moving stem to the outside meets Gasunie’s objectives for underground installations. The integrated servo-electric actuator allows Gasunie to perform better control, resulting in the reduction of emissions elsewhere, such as those caused by pneumatic controllers and even by compressors.
The Zero emission valve consumes very little power. The elimination of stem seal friction in combination with Mokveld’s trademark fully pressure balanced design reduces forces when moving. Power consumption over the valve’s lifetime is reduced by cutting power under steady-state conditions, using a self-braking drive nut. These features contribute towards achieving Gasunie’s Scope 2 GHG goals.
The Zero emission valve is suitable for natural gas, hydrogen, carbon dioxide, and other future fluids, ready for the future of Gasunie to supply reliable energy in the region.
