Valve Seat (Conical Sealing Face)
Precision seat body with a conical sealing face where a needle or ball valve seats.
Manufacturing Scope
Valve Seat (Conical Sealing Face) is a Valve Parts family precision-turned on a Goodway SW-20, covering 10 variants — diameters ⌀6–20 mm, lengths 10–31 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 VALB-SET-20 at 31 mm. Besides turning, the family requires taper turning. Bores in this family run ⌀1.5–10.5 mm. 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 VALB-SET-04: 10 mm long at ⌀6 mm, L/D 1.7. A short, rigid body: what governs the result here is not deflection but diameter tolerance and surface finish.
Variants are machined to H6 tolerance; the smallest is VALB-SET-04 (⌀6 mm) and the largest VALB-SET-20 (⌀20 mm). The family includes tapered, bored, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
This is a dimension schematic, not a manufacturing drawing. Dimensions match the catalog data; request a quote with the part code to confirm before production.
