Abstract

A pressure control valve unit () for a fluid with at least one inlet area (P) and first and second outlet areas (A, T) which can be connected for fluid flow with one another by two mutually coupled seat valves (). An incoming fluid flow, from the inlet area (P) to the first and second outlet areas (A, T), can be adjusted by way of the first seat valve (), and a fluid outflow, between the first and second outlet areas (A,T), can be adjusted by way of the second seat valve (). In this case, a flow-guiding device () is arranged, upstream from the first seat valve () in the inlet area (P), and imposes a specific flow characteristic upon the inflowing fluid in the area of the first seat valve ().
