Descripción de producto
Custom Steam Turbine Oil Actuator Valve Spool
The valve spool serves as the critical sliding core component within steam turbine oil motor actuators. It precisely controls steam flow through hydraulic displacement to regulate turbine output speed and load. Our specialized manufacturing delivers high-precision, long-service-life sliding components for thermal power, cogeneration, and industrial steam turbine applications worldwide.
Customization Capabilities
We provide comprehensive personalized solutions based on customer specifications:
  • Custom dimensions including overall length, shaft diameter, flange positioning, and oil hole distribution
  • Specialized groove configurations: balance grooves, damping grooves, and sealing step structures
  • Material selection: 40Cr, 42CrMo, nitriding steel, stainless alloy steel
  • Surface strengthening processes: gas nitriding, hard chromium plating, mirror superfinishing
  • Custom tolerance grades to meet high-pressure EH oil system sealing requirements
Performance Features
Excellent Motion Smoothness
Ultra-precision cylindrical grinding and mirror superfinishing achieve minimal surface roughness. Perfect concentricity and roundness ensure friction-free sliding with valve sleeves, preventing valve jitter, sticking, and regulating deviation under variable load conditions.
Exceptional Durability & Anti-Corrosion
Special surface hardening creates a dense wear-resistant layer that resists erosion and oxidation from high-temperature turbine EH oil. Reduces wear clearance and internal leakage during long-cycle operation, minimizing maintenance frequency.
Stable Hydraulic Control Accuracy
Symmetrical oil channel layout and precision-machined throttling edges ensure linear hydraulic response. Maintains consistent flow control accuracy during frequent start-stop cycles and load fluctuations, enhancing overall unit operation stability.
Quality Control System
Every customized valve spool undergoes comprehensive multi-stage inspection:
Inspection Stage Testing Parameters
Raw Material Analysis Composition analysis and hardness testing
Dimensional Verification Full dimension coordinate measurement
Geometric Tolerance Concentricity, straightness, and roundness detection
Surface Integrity Defect penetration inspection
Performance Validation Hydraulic matching simulation with paired valve sleeves
All test reports accompany delivered goods for complete traceable quality management.
