Hereinafter, a method of manufacturing the valve device 10 will be described. In FIGS. 5 to 14, a variant of the spacer unit 22 is shown, in which, as mentioned, the spacer unit 22 'has no latching connections between the first spacer element 24' and the second spacer element

28 ', but fixing elements not shown in detail, which implement an anti-rotation. The spacer unit 22 'and its spacer elements 24', 28 'are therefore provided with primed reference numerals. However, a manufacturing method of the valve device 10 is analogous to the spacing unit 22 shown in FIGS. 1 to 4. FIG. 5 shows the valve body unit 12 in a first preassembled state in a schematic sectional representation. In a first method step, the valve body unit 12 is provided with a first sealing element 58. FIG. 6 shows the valve body unit 12 in a second preassembled state in a schematic sectional view, in which the first sealing element 58 is attached to the valve body unit 12. The first sealing member 58 is attached to the first valve body 14. The first sealing element 58 is provided to allow a tight fit of the first valve body 14 in the first valve seat 26 '. FIG. 7 shows the first spacer element 24 'of the spacer unit 22' in a first preassembled state in a schematic sectional representation. In a second method step, the spacer element 24 'is provided with a second sealing element 60. The second sealing element 60 is provided for sealing a connection of the first valve seat 26 'to the flow housing 38. FIG. 8 shows the first spacer element 24 'in a second preassembled state in a schematic sectional representation, in which the sealing element 60 is arranged on the first spacer element 24'. In a third method step, the first spacer element 24 'is provided with a third sealing element 62. FIG. 9 shows the first spacer element 24 'in a third preassembled state in a schematic sectional representation, in which the third sealing element 62 is arranged on the first spacer element 24 '.

FIG. 10 shows the first spacer element 24 'and the valve body unit 12 in a preassembled state in a schematic sectional illustration. In a fourth method step, in the preassembled state, in which the first valve body 14 carries the first sealing element 58, the valve body unit 12 is inserted into the first spacer element 24 '. The valve body unit 12 is placed in the first valve seat 26 '.

FIG. 11 shows the second spacer element 28 'of the spacer unit 22' in a first preassembled state in a schematic sectional representation. In a fifth method step, the second spacer element 28 'is provided with a fourth sealing element 64. FIG. 12 shows the second spacer element 28 'in a second preassembled state in a schematic sectional representation, in which the fourth sealing element 64 is fastened to the second spacer element 28'. The fourth sealing element 64 is associated with the second valve seat 30 '. The fourth sealing element 64 is provided for sealing a connection between the second valve seat 30 'and the flow housing 38. The fourth sealing element 64 may be formed as a laterally sealing sealing ring or as a flat gasket.

FIG. 13 shows the spacer unit 22 'and the valve body unit 12 in a first preassembled state in a schematic sectional representation. The second spacer element 28 'provided with the fourth sealing element 64' is connected to the first spacer element 24 'in a sixth method step, in particular also latched as in the case described above. In a connected state, the first spacer element 24 'is non-rotatably connected to the second spacer element 28'. It is also conceivable that initially the two

Distance elements 24 ', 28' are connected and then the preassembled valve body unit 12 is inserted. In the first preassembled state of the valve body unit 12 and the spacer unit 22 ', the valve body unit 12 is in an installed position of the valve body unit 12. The installation position corresponds to an installed position in a mounted state of the valve body. 10. The installation position corresponds in particular to a relative position of the valve body unit 12 to the first valve seat 26 and / or to the second valve seat 30 in an assembled state, in which the spacer unit 22 and the valve body unit 12 are arranged in particular in the flow housing 38.

In a seventh method step, the valve body unit 12 is provided with a fifth sealing element 34. FIG. 14 shows the spacer unit 22 'and the valve body unit 12 in a second preassembled state in a schematic sectional view, in which the fifth sealing element 34 is fastened to the valve body unit 12. In particular, the second valve body 16 is provided with the fifth sealing element 34. The fifth sealing element 34 is intended to allow a tight fit of the second valve body 16 in the second valve seat 30 '. The second valve body 16 is first positioned in the second valve seat 30 'and then provided with the fifth sealing element 34.

For this purpose, a low assembly force is advantageously sufficient, in particular a force which is less than a force occurring on a lifting rod during compression of a separately formed valve body. In an eighth method step, the actuating element 20 is materially connected to the valve body unit 12. Alternatively or additionally, it is conceivable that the actuating element 20 is positively connected to the valve body unit 12. For this purpose, the actuating element 20 is pushed into the receiving region 52 parallel to the main extension direction 51 of the valve body unit 12. The actuating element 20 is ultrasonically welded to the valve body unit 12, in particular to the receiving element 54 of the first valve body 14. An assembly of the actuating element 20 can take place in particular outside of the flow housing 38. An arrangement of the actuating element 20 relative to the valve body unit 12 is adjusted by means of the Abstandseinheit 22. In particular, the valve body unit 12, the

Distance unit 22 and the actuator 20 according to a relative arrangement, which corresponds to a relative arrangement in the assembled state, inserted into the flow housing 38. It is thus advantageously possible to use identical actuator units and / or actuating elements by means of using different rather spacer units are combined with different flow housings.

In particular, a different sequence of method steps and / or a different number of sealing elements is conceivable for the described method. One

Bending an actuating element can be advantageously avoided by a first valve body and a second valve body are first arranged in their associated valve seats and then only a sealing element is attached.

According to a further aspect, at least one of the valve bodies 14, 16 may have a substantially peripheral groove for receiving a sealing element 34, 58. In FIGS. 5 and 6, both valve bodies 14, 16 have a groove. The groove of the valve body 14 and / or of the valve body 16 serves, in particular partially, to accommodate at least one sealing element 58. FIG. 6 shows the valve body unit 12 in a second preassembled state in a schematic sectional representation, in which the first sealing element 58 abuts the valve body unit 12 is mounted. The first sealing member 58 is attached to the first valve body 14. The sealing element 58 is mounted in the, in particular completely, circumferential groove of the valve body 14. The sealing element 58 is located in the radial direction only to a part within the groove.

According to another aspect, the opening, or the width of the groove increases in the radial direction. The groove is trapezoidal in cross section. The groove base is advantageously formed substantially parallel to the longitudinal axis of the valve body unit 12. At least one of the groove walls / groove edges runs obliquely to the groove bottom. The angle between the groove bottom and groove walls is between 90 degrees and 150 degrees, preferably 100 to 150 degrees. In FIGS. 2, 5, 6 and 10 there is shown by way of example a valve body 14, 16 with groove walls which have the same slope with respect to the groove bottom. The sealing element

58 is in the mounted state of the groove bottom and the two groove walls. Due to the oblique formation of the groove walls load peaks are lower. The sealing element 58 is not pressed by the bevel on the peripheral edge of the valve body 14, 16 formed on the radially outer end. According to a further aspect, the groove walls have a part running obliquely in relation to the groove bottom and radially further outside a part running perpendicular to the groove bottom. The groove walls have an angled portion. An angling in the groove walls is shown in FIG. 2 as an example.

According to a further aspect, at least one of the valve bodies 14, 16 adjoins at least one of the groove walls, in particular radially outwardly, a region extending parallel to the groove bottom. Following the area of the valve body 14, 16 is formed as a truncated cone. The truncated cone is formed so that it can be inserted into the valve seat 26, 30. The sealing element 58 is provided to allow a tight fit of the first valve body 14 in the first valve seat 26. The sealing element 34 is provided to allow a tight fit of the second valve body 16 in the second valve seat 30.

The sealing element 58 has in particular an elliptical cross section, as shown in particular in FIG. 6. For mounting the sealing element 58, this is stretched to.
