A fluid control device comprising a housing with at least one first port having a first main axis and at least one second port (18, 20) having a second main axis (24, 26), (i) wherein a valve body is enclosed in the housing, the valve body being arranged between the at least one first port and the at least second port (18, 20), (ii) the valve body providing a fluid path having a first path portion proximal to the first port and an opposing second path portion in a distance from the first port and proximal to the at least one second port (18, 20), the fluid path being switchable between at least a first position and at least a second position by rotating the valve body around the first main axis of the at least one first port, (iii) wherein a first sealing means is provided at the first path portion and a second sealing means is provided at the second path portion, (iv) the first sealing means having a first first-sealing-means interface portion for cooperating with the valve body and a second first-sealing-means interface portion for cooperating with the housing, and the second sealing means having a second second-sealing-means interface portion for cooperating with the valve body and a first second-sealing-means interface portion for cooperating with the housing, (v) wherein the valve body is provided with a first valve-body interface portion for cooperating with the first first-sealing-means interface portion, one of which being configured as a spherical interface and one of which being configured as a conical or a spherical interface, (vi) wherein the valve body is provided with a second valve-body interface portion for cooperating with the second second-sealing-means interface portion, one of which being configured as a spherical interface and one of which being configured as a conical or a spherical interface, (vii) and wherein the housing is provided with a first housing interface portion for cooperating with the second first-sealing-means interface portion and a second housing interface portion for cooperating with the first second-sealing-means interface portion, one of the second housing interface portion and the first second-sealing-means interface portion being configured as a spherical interface and the other one being configured as a conical or a spherical interface. (i) wherein a valve body is enclosed in the housing, the valve body being arranged between the at least one first port and the at least second port (18, 20), (ii) the valve body providing a fluid path having a first path portion proximal to the first port and an opposing second path portion in a distance from the first port and proximal to the at least one second port (18, 20), the fluid path being switchable between at least a first position and at least a second position by rotating the valve body around the first main axis of the at least one first port, (iii) wherein a first sealing means is provided at the first path portion and a second sealing means is provided at the second path portion, (iv) the first sealing means having a first first-sealing-means interface portion for cooperating with the valve body and a second first-sealing-means interface portion for cooperating with the housing, and the second sealing means having a second second-sealing-means interface portion for cooperating with the valve body and a first second-sealing-means interface portion for cooperating with the housing, (v) wherein the valve body is provided with a first valve-body interface portion for cooperating with the first first-sealing-means interface portion, one of which being configured as a spherical interface and one of which being configured as a conical or a spherical interface, (vi) wherein the valve body is provided with a second valve-body interface portion for cooperating with the second second-sealing-means interface portion, one of which being configured as a spherical interface and one of which being configured as a conical or a spherical interface, (vii) and wherein the housing is provided with a first housing interface portion for cooperating with the second first-sealing-means interface portion and a second housing interface portion for cooperating with the first second-sealing-means interface portion, one of the second housing interface portion and the first second-sealing-means interface portion being configured as a spherical interface and the other one being configured as a conical or a spherical interface.
