Product Description

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.
