Self-venting pressure regulating valve for fluid mediums e.g. for water/gas supply, has valve in main duct pressure-actuated by medium-controlled valve control unit

摘要

A pressure regulating valve for fluid mediums has a main passage (23) for the medium in which a valve is arranged, which is pressure-actuated by a medium-controlled valve control unit (112), in which the latter has at least one control line (11,12) for the control medium. The control line (11,12) discharges in the region of the highest point of the medium supply in the valve control unit (112).
