A hydraulic control slider arranged longitudinally displaceably in a housing bore of a hydraulic valve, the control slider comprising:
- a middle portion having a number of control edges;
- and
- two end portions each arranged on either side of the middle portion,
- wherein one end portion of the two end portions comprises a radially outwardly protruding control slider integral lug.
A hydraulic valve comprising:
- a valve housing defining a housing bore;
- and
- a control slider movably mounted in the housing bore along a longitudinal axis,
- wherein the control slider comprises an anti-rotation lock configured to protrude radially outward from the control slider
- wherein the anti-rotation lock is accommodated in a guide groove of a pole tube mounted on the valve housing,
- wherein the anti-rotation lock is configured to prevent rotation of the control slider about the longitudinal axis relative to the valve housing, and
- wherein the anti-rotation lock is a control slider integral lug.
A manufacturing process for a control slider for a hydraulic valve, the process comprising:
- machining the control slider from a raw material, including machining a control slider integral lug of the control slider as an integral part of the control slider;
- and
- heat treating the machined control slider to harden the control slider.
