A valve housing blank comprises a receiving space for a valve insert having a longitudinal axis. At least two first pairs of supply ducts, which are opposite to each other with respect to the longitudinal axis, extend laterally from an outer side of the blank towards the receiving space. The pairs of supply ducts, as seen in the direction of the longitudinal axis, are arranged so as to be offset relative to each other. Only one of the supply ducts is open towards the receiving space. The other supply ducts are closed off from the receiving space by a destroyable dividing wall.

1. A valve housing blank, comprising: a receiving space for a valve insert having a longitudinal axis;at least two first pairs of supply ducts which are opposite to each other with respect to the longitudinal axis and extend laterally in a radial direction from an outer side of the valve housing blank towards the receiving space;the at least two first pairs of supply ducts, as seen in the direction of the longitudinal axis, being arranged offset relative to each other;wherein only one supply duct is open towards the receiving space, the other ducts being closed off from the receiving space by a destroyable dividing wall;laterally outward extending spacers formed on sides of the supply ducts;wherein supply ducts in an outward direction terminate in a planar end face and the spacers terminate in a plane of the end faces to form a contact surface; andwherein each spacer extends up to two planes defined by end faces and terminates at the end face to form one contact surface each. 2. A valve assembly comprising: several adjoining valve housings made up of valve housing blanks that each comprisea receiving space for a valve insert having a longitudinal axis,at least two first pairs of supply ducts which are opposite to each other with respect to the longitudinal axis and extend laterally in a radial direction from an outer side of the valve housing blank towards the receiving space,the at least two first pairs of supply ducts, as seen in the direction of the longitudinal axis, being arranged offset relative to each other, andwherein only one supply duct is open towards the receiving space, the other supply ducts are each closed off from the receiving space by a destroyable dividing wall; andthe destroyable dividing walls are at least partially removable to form continuous ducts and to provide a flow connection between several of the supply ducts. 3. A valve housing blank, comprising: a receiving space for a valve insert having a longitudinal axis;at least two first pairs of supply ducts which are opposite to each other with respect to the longitudinal axis and extend laterally in a radial direction from an outer side of the valve housing blank towards the receiving space;at least one further double pair of supply ducts which are opposite each other with respect to the longitudinal axis and extend laterally in a radial direction from the outer side of the blank towards the receiving space;the at least two first pairs of supply ducts and the at least one further double pair of supply ducts as seen in the direction of the longitudinal axis, being arranged offset relative to each other; andwherein only one supply duct per each double pair is open towards the receiving space, the other supply ducts being closed off from the receiving space by a destroyable dividing wall. 4. The valve housing blank according to claim 3, wherein the two first pairs of supply ducts, with respect to a respective duct axis, are situated in a plane that is perpendicular to the longitudinal axis. 5. The valve housing blank according to claim 3, wherein the further double pair of supply ducts, with respect to a respective duct axis, also lies in a plane that is perpendicular to the longitudinal axis. 6. The valve housing blank according to claim 3, wherein the two first pairs of supply ducts and the at least one further double pair of supply ducts comprise axially superimposed supply ducts. 7. The valve housing blank according to claim 3, wherein an open supply duct of the first pairs of supply ducts, with respect to the longitudinal axis, is provided on a diametrically opposite side, but axially offset relative to an open supply duct of the further double pair of supply ducts. 8. The valve housing blank according to claim 3, wherein associated pairs of supply ducts are perpendicular to each other. 9. The valve housing blank according to claim 3, wherein the first pairs and/or the at least one further double pair of supply ducts each have spacers that lie in a plane defined by axes of the associated supply ducts. 10. The valve housing blank according to claim 3, wherein at least one open supply duct terminates at an outer end with a widening of its cross-section. 11. The valve housing blank according to claim 3, wherein the receiving space terminates in a front-side wall which is a destroyable dividing wall, with an axial supply duct terminating at an opposite side of the dividing wall. 12. The valve housing blank according to claim 3, wherein the receiving space terminates in an outward direction in a planar flange face, another parallel flange face being provided at an opposite side of the blank, and with the flange faces, the end faces, and the contact surfaces being arranged in surface areas of a cuboid with a square base area. 13. The valve housing blank according to claim 3, wherein the dividing wall directly adjoins the receiving space. 14. The valve housing blank according to claim 3, wherein the valve housing blank is formed as a stainless steel precision casting. 15. The valve housing blank according to claim 3, wherein a valve seat produced by casting is formed in a supply duct. 16. The valve housing blank according to claim 3, wherein the supply ducts are realized as tubular protrusions. 17. The valve housing blank according to claim 16, wherein axially superimposed protrusions are connected to each other by an integrally formed rib. 18. The valve housing blank according to claim 17, wherein the ribs extend radially with respect to the longitudinal axis. 19. The valve housing blank according to claim 17, wherein a fastening recess is cast in the ribs. 20. The valve housing blank according to claim 3, including laterally outward extending spacers formed on sides of the supply ducts. 21. The valve housing blank according to claim 20, wherein the spacers extend up to a radially outer ends of the supply ducts. 22. The valve housing blank according to claim 20, wherein the spacers are formed as radial ribs that are situated in a plane perpendicular to the longitudinal axis. 23. The valve housing blank according to claim 20, wherein supply ducts in an outward direction terminate in a planar end face and the spacers terminate in a plane of the end faces to form a contact surface. 24. The valve housing blank according to claim 23, wherein the end faces of the supply ducts and/or the contact surfaces are provided on sides of a square as seen in the longitudinal direction.
