Functional description

The GEMÜ N082 and N182 pressure
reducers ensure that a constant outlet
pressure is maintained in process plant
utilizing the pressure differential. If the
pressure rises on the outlet side, the spring
force is lower and the valve closes as the
spring is raised. The pressure is reduced
until the spring force and the outlet pressure
are the same. If the pressure falls, the valve
opens as the spring force presses against
the diaphragm surface via the control
aperture. The outlet pressure can be read
off a diaphragm-protected pressure gauge
and the spring force adjusted using a set
screw as required.
