Abstract
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.

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;
- and
- wherein each spacer extends up to two planes defined by end faces and terminates at the end face to form one contact surface each.
A valve assembly comprising:
- several adjoining valve housings made up of valve housing blanks that each comprise
- 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, and
- wherein 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;
- and
- the destroyable dividing walls are at least partially removable to form continuous ducts and to provide a flow connection between several of the supply ducts.
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;
- and
- wherein 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.
