    A pressure relief valve with DN125 nominal diameter, pressure rating is PN16, the shell test pressure is 2.4 MPa. The pressure reducing valve automatically opens at a set pressure and provides proportional and slow pressure relief.


    • Pilot-operated valves for limiting a system pressure
    • Operation using proportional solenoid
    • Maximum pressure limitation
    • Valve and control electronics from a single source
    • Little manufacturing tolerance of the command value
    • Pressure characteristic curve

    Tips: What is the difference between a direct and pilot-operated relief valve?

    The main difference between direct-acting and pilot solenoids is that direct-acting solenoid valves have a direct connection with the opening and closing armature, whereas pilot-operated valves employ the use of the process fluid to assist in piloting the operation of the valve.
