  • GEMU N082 Pressure Reducer Control Valve

    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

  • GEMU N185 Pressure Relief Control Valve

    The pressure relief valves GEMU N085 and N185 protect the plant and the piping system against gauge pressure and reduces pressure peaks. The third pipe spigot enables the valve to be installed in the main pipe. If the pressure increases, the spring is raised and the valve opens. The pressure is reduced to the preset value and can escape via the third pipe spigot into an adjacent pipe. If the pressure falls, the spring force presses the diaphragm in the direction of the seal seat and it is closed. The spring force can be adjusted as required using a set screw.

    • Valve adjustments can also be made under working pressure.
    • The optimization of piston, springs and control face ensures good control characteristics
    • The actuator is hermetically separated from the medium

  • GEMU N786 Pressure Retaining Control Valve

    The GEMU N086, N186 and N786 pressure retaining valves are used to provide a constant back pressure in process plant. If the inlet pressure rises above a preset value, the diaphragm is raised against the spring force. The valve opens and the excess pressure can escape into the outlet line. If the pressure on the inlet side is reduced, the valve closes as the spring force pushes the diaphragm against the seal seat. The spring force can be adjusted as required using a set screw and secured with the lock nut.

    • 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
