Pressure Control Valves

Our pressure control valves from PVC, PP or PVDF (further materials available upon request) reduce system pressure to a defined value. They are available with widths of DN10–DN100. Using differential pressure, the pressure reducer adjusts itself to the set operating pressure. There is no direct relation between the outlet and inlet pressure. The output point acts on the membrane surface via a control bore, pushing against the set spring force. When an equilibrium of forces has been reached, the valve closes and maintains a constant operating pressure. If the pressure on the output side falls, this means that the set spring force is greater. The valve opens to restore the equilibrium.
