The GEMU N082, N182 and N782 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 (not available for N782) and the spring force adjusted using a set screw as required.
- The working pressure can be very easily adjusted using a set screw and secured with the integrated lock nut. If required, the setting that has been made can be lead sealed
- The flow-efficient design of the valve body ensures good flow rate values
- Control errors are kept to a minimum due to the large Control face and the spiral spring
- The actuator is hermetically separated from the medium
