Product Specification
Custom Main Steam Control Valve Stems for Steam Turbines
Product Overview
Our tailor-made main steam control valve stems are core critical moving components for supercritical & ultra-supercritical steam turbine main steam valves, widely used in thermal power plants, cogeneration units and industrial steam turbine systems.
Manufactured via integral die forging and ultra-precision CNC machining, each valve stem is fully customized based on customers' drawings, unit parameters and extreme operating conditions. It precisely transfers actuator driving force to adjust steam flow, stabilize turbine power output and maintain reliable sealing under long-cycle frequent opening/closing operations in high-temperature, high-pressure main steam environments.
Core Customization Strengths
Full Customization Service
Customize overall length, stepped shaft structure, thread size, sealing journals, gear tooth section and conical valve head
Support OEM & ODM for all mainstream turbine brands
Multiple surface strengthening treatments optional: QPQ nitriding, hard chrome plating, Stellite alloy surfacing, electroless nickel plating
Premium Heat-Resistant Alloy Materials
We select materials according to your actual working temperature (540℃ / 566℃ / 600℃+) and pressure (16-32MPa):
Material Type
Examples
Heat-resistant alloy steel
12CrMoV, F91, F92, 35CrMoA
Martensitic stainless steel
12Cr13, 17-4PH
High-temperature superalloy
For ultra-supercritical harsh working conditions
Full material test certificates (MTC), chemical composition and mechanical property reports provided for every batch.
Advanced Manufacturing Technology
Integral open-die forging eliminates casting defects like pores and segregation, optimizes internal metal grain flow
Ultra-precision cylindrical grinding for matching surfaces, tolerance controlled within ±0.002mm
Mirror polished shaft surface reduces friction, effectively prevents valve sticking
Excellent Performance Under Extreme Conditions
High Temperature Stability
Consistent mechanical properties under 500-620℃ superheated steam
High Pressure Resistance
Adaptable to ultra-high pressure main steam pipelines
Extended Service Life
3-5 times longer service cycle than standard valve stems, cutting power plant maintenance downtime and spare parts costs
Strict Quality Inspection System
Raw material incoming test: Spectrum analysis, hardness test, ultrasonic flaw detection
Semi-finished product inspection: Full dimension measurement via coordinate measuring machine (CMM)
Surface treatment performance test: Hardness, wear resistance and high-temperature oxidation simulation tests
