Product Description

The Forged Valve Shaft ensures precise torque transfer and rotational alignment in medium- to large-scale hydropower valves. Made from carbon or Alloy Steel, it offers excellent torsional rigidity, fatigue resistance, and dimensional stability in high-pressure hydraulic environments.

Manufacturing Focus for Valve Shaft

The valve shaft is forged with emphasis on torsional strength, concentricity, and cross-sectional integrity, supporting stable torque transmission within large valve drive systems. Open-die forging allows controlled material distribution along stepped or varying diameters, enhancing resistance to combined torsional and bending loads commonly encountered during valve actuation.

Machining operations are applied selectively to bearing interfaces, coupling sections, and reference diameters, ensuring proper alignment with drive mechanisms while maintaining overall structural robustness.

Typical Applications

Torque transmission shafts for hydropower valves
Industrial valves needing high torsional strength
Pumps, compressors, and mechanical drive systems

Forged valve shafts are used in rotational drive systems of hydropower and large industrial valves, transmitting torque from actuators or gear mechanisms to internal valve components.

They are typically applied in butterfly valves, large gate valves, and other heavy-duty valve assemblies where rotational stability, mechanical strength, and long-term load resistance are critical.

For customers sourcing critical forged shafts, rings, or Transmission Components, a documented traceability system is essential.

Our identification and traceability management practices provide transparent quality evidence and support long-term, reliable cooperation.
