VALVE, IN PARTICULAR A PRESSURE REGULATING VALVE OR PRESSURE LIMITING VALVE

摘要

A valve (1), in particular a pressure regulating valve or a pressure limiting valve for controlling a pressure of a medium (3) that flows through the valve (1), includes a main stage (5) and a pilot stage (7) that actuates the main stage (5). The main stage is actuated against the effect of a restoring device (11) by an energizable actuating device (9). A pressure release stage (13) of the valve (1) has a surface area modification device (15).
