Valve Spring Pin

Manufacturing Scope

Valve Spring Pin is a Valve Parts family precision-turned on a Goodway SW-20, covering 10 variants — diameters ⌀6–20 mm, lengths 20–51 mm, standard material Stainless Steel (also steel, stainless, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request an instant quote with the code you need.

The family is machined from ⌀20 mm bar stock; its longest variant is VALA-YSP-18 at 51 mm. Besides turning, the family requires thread turning (M5). All of it is completed in a single setup, without the part leaving the machine.

The variant with the highest length-to-diameter ratio is VALA-YSP-05: 23.5 mm long at ⌀7 mm, L/D 3.4. This ratio is achievable on a conventional lathe as well; the sliding-head advantage in series work is that the part never leaves the machine, so the size does not drift from variant to variant.

Variants are machined to h9, 6g tolerance classes; the smallest is VALA-YSP-04 (⌀6 mm) and the largest VALA-YSP-18 (⌀20 mm). The family includes threaded, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
