Control Valves, industrial
22-4
Pressure regulator, DR300
Pressure regulators of this type protect downstream installations against excessive supply pressure.
Pressure regulators are used when the capacity of direct controlled pressure reducing valves are
insufficient. Their compact construction makes them particularly suitable for installation in limited
spaces, for example in ducts. By using a pressure regulator, pressurization damage is avoided and
water consumption reduced. The set pressure is also maintained constant, even when there is wide
inlet pressure fluctuation. Reduction of the operating pressure and maintaining it at a constant level
minimizes flow noise in the installation.
