  • Pressure-limiting valve

    Pressure-limiting valveHYDRAULIcs & Mining technology

    Pressure-limiting valves have the function of limiting the pressure in hydraulic work cylinders to a specified maximum (pressure setting).

    The sealing principle in piston valves is the sealing of a piston by means of a piston sealing ring. The closing force of the valve is produced by a compression spring. The piston remains closed until the pressure exceeds the set spring force. The emulsion flows either out into the surroundings or into the return line.
