The GEMÜ N082 pressure reducer ensures that a constant outlet pressure is maintained in process plants by utilizing the pressure differential. If the pressure increases on the outlet side, the spring force is lower and the spring is raised, closing the valve. The pressure is reduced until the spring force and the outlet pressure are the same. If the pressure falls, the spring force presses against the diaphragm surface via the control aperture, opening the valve.
Depending on requirements, the outlet pressure can be read off a diaphragm-protected pressure gauge and the spring force adjusted using a set screw.
