German MvD Gasarmaturen valves MvD Gasarmaturen models MvD Gasarmaturen prices

MvD Gasarmaturen valves are valves that reduce inlet pressure to a required outlet pressure through regulation, and rely on the energy of the medium itself to automatically maintain stable outlet pressure. From the perspective of fluid mechanics, a pressure reducing valve is a throttling element with variable local resistance, i.e., by changing the throttling area, the flow velocity and kinetic energy of the fluid are changed, causing different pressure losses, thereby achieving pressure reduction. Then, through the regulation of the control and adjustment system, the fluctuation of the pressure after the valve is balanced with the spring force, keeping the pressure after the valve within a certain error range.
