Claim 10:
11. A valve housing (105) for a hydraulic control valve, comprising:
a base body (100);
a plurality of valve pockets (13, 140, 150) formed in the base body (100) from a coupling side, the valve pockets (13, 140, 150) configured for guiding a hydraulic fluid, the valve pockets (13, 140, 150) delimited and/or separated from one another by web sections (180); and
a valve spool chamber (110) formed in the base body (100), the valve spool chamber (110) configured for receipt of a valve spool, the valve spool chamber (110) defining a longitudinal axis (L), the valve spool chamber (110) extends through at least one web section (180) to form a web exit opening (200), the web exit opening (200) opening into a machining valve pocket (190) of the valve pockets (120, 140), the web exit opening (200) circumferentially delimited by a control edge (170), the control edge (170) formed by a spool guiding section (210) and a front-side section (220),
wherein the front-side section (220) of the control edge (170) of the base body (100) is produced with a cutting process, and a cutting tool is guided from the coupling side through the machining valve pocket (190) to the front-side section (220) of the control edge (170) in the cutting process, and
wherein the base body (240) comprises a web wall area (250) in the machining valve pocket (190), the web wall area (250) comprises a front-side section (260) and a residual web wall section (270), and the front-side section (260) protrudes axially over the residual web wall section (270) with respect to a spool direction and/or the longitudinal axis (L).
