Custom CNC Stainless Steel Machined Shaft for Valves

Valve Assembly Valve Stem Precision Stainless Steel Machined Shaft

Material: Stainless steel (such as SUS304/SUS316) or alloy steel

Shape: Overall precision cylindrical shaft structure, with stepped shafts, locating shoulders, or end flanges in some areas.

Size Range: Diameter typically ranges from Φ3 mm to Φ30 mm; length can be customized.

Internal Design: The valve stem has a dense internal structure with no cavities, ensuring high strength and fatigue resistance.

Surface Treatment: Surfaces can be finely polished, mirror-polished, passivated, or finely ground to reduce the coefficient of friction.

Manufacturing Process: Machined using high-precision turning and precision grinding processes, with strict tolerance control for key dimensions; combined with full-process quality inspection.
