Product Description

Our Forged Valve Stem is designed to provide reliable actuation and long-term operational stability for hydropower valves. Manufactured from high-quality carbon or Alloy Steel, it ensures torsional strength, wear resistance, and dimensional accuracy under demanding hydraulic conditions.

Manufacturing Focus for Valve Stem

The forging and finishing process of the valve stem is primarily oriented toward achieving stable axial straightness, precise thread geometry, and reliable surface integrity along the full length of the component.

Material flow during forging is controlled to align with the stem axis, minimizing internal stress concentration and ensuring consistent performance under repeated axial movement during valve operation.

Subsequent machining operations focus on thread accuracy, surface smoothness in sealing-related areas, and dimensional consistency, supporting reliable engagement with actuators and valve discs.

Quality Control & Traceability

All forged components are manufactured under a controlled identification and traceability system. Each product is uniquely marked and traceable from raw material heat number through forging, Heat Treatment, machining, inspection, and final delivery.

For a detailed explanation of how we manage product identification, inspection status, and reverse traceability throughout the forging lifecycle, please refer to our

Typical Applications

Hydropower turbine valve stems
Industrial valve systems requiring accurate actuation
Heavy-duty hydraulic equipment needing reliable stem performance

Forged valve stems are used as control elements in hydropower and industrial valve assemblies, where precise axial motion is required to open, close, or regulate fluid flow. They are commonly applied in gate valves, globe valves, and regulating valves operating under medium to high pressure, where dimensional stability and thread reliability directly affect control accuracy and service life.
