A double check valve (100) includes a sleeve (10) with a first inlet opening (11), a second inlet opening (12), an outlet opening (13), and a guide piece (20). The guide piece (20) movable along the longitudinal axis (L) within the sleeve (10), by loading with a fluid-induced pressure, between a first blocking position (S1) and a second blocking position (S2) spaced therefrom, wherein each of the inlet openings (11, 12) is closed at least partly fluid-tightly by the guide piece (20) in one of the blocking positions (S1, S2). The double check valve (100) has a permanent magnet (30, 31, 32, 33), and the guide piece (20) and the permanent magnet (30, 31, 32, 33) are configured to magnetically deflect the guide piece (20) from an intermediate position (Z) arranged between the blocking positions (S1, S2) and/or from one of the two blocking positions (S1, S2).
