Beschreibung
Zusammenfassung:	A valve includes a housing, in which a first valve body is accommodated so that it is moveable in a direction of a longitudinal axis, a first valve seat configured to be closed by the first valve body and arranged on the housing, a first fluid flow path extending from a first connection via the first valve seat to a second connection, a second valve seat closeable by a moveable second valve body, the second valve body formed separately from the first valve body, a second fluid flow path extending from the first connection via a bypass duct in the first valve body, onwards via the second valve seat to the second connection, so that pressure at the first connection is limited upwardly by the first and the second valve body in that hydraulic fluid is led to the second connection via the first fluid flow path.
