A pressure reducer for fluid lines, with a sealing piston (70, 110) as stop element, with an equalization piston (20a, 190) as a means for pressure equalization, with a single-part or multi-part connecting means (20b, 90, 200) by which the sealing piston (70, 110) and the equalization piston (20a, 190) are rigidly connected with one another, with a valve seat, in conjunction of which the sealing piston (70, 110) defines a flow-through opening, against which the sealing piston (17, 110) seals when the valve is closed and which the connecting means (20b, 90, 200) penetrates, and with guide means (20c, 210) which are directly or indirectly rigidly coupled with the connecting means and guide an arrangement composed of at least the equalization piston (20a, 190), connecting means (20b, 90, 200) and sealing piston (70, 110) in each operating position, wherein the guide means (20c, 210) are arranged in the region of the valve seat between the sealing piston (70, 110) and the equalization piston (20a, 190). |
