Description

Valve Stem designed for water valve applications, providing precise movement and reliable sealing. The slotted and two-flat dimensions are formed through a one-step cold heading process, ensuring high dimensional accuracy, uniform strength, and excellent surface quality without secondary machining.

Made from 304HC2 stainless steel (AISI 304 equivalent), this Valve Stem offers superior corrosion resistance, wear resistance, and long-term durability in water systems. With an overall dimension of φ20.5 × 23.30 mm and precise slotted/two-flat specifications (φ13.84 ±0.1 mm × 5.89 ±0.08 mm; φ15.70 ±0.08 mm × 9.4 -0.1 mm × 7.7 mm), it guarantees smooth operation, stable torque transmission, and reliable performance in valves for plumbing and water control systems.
