Abstract:
1. A method for operating a pressure reducer, the method comprising: providing a pressure reducer having a high-pressure inlet, a low-pressure outlet, a valve having a valve seat and a valve plunger which interacts therewith, the valve plunger configured for displacement in a displacement direction such that, when displaced away from the valve seat, the valve plunger opens a first path between the high-pressure inlet and the low-pressure outlet, and a second path operatively connecting the high-pressure inlet and the low-pressure outlet; adjusting, via a first control valve, a first control pressure acting on a first effective area of the valve plunger and resulting in a first force acting on the first effective area in the displacement direction away from the valve seat, wherein the first effective area and the first control valve are arranged in the second path; and adjusting, via a second control valve, a second control pressure on a second effective area of the valve plunger which is spatially arranged in the second path, thereby resulting in a second force acting on the second effective area in a second displacement direction towards the valve seat, the second force acting counter to the first force.
