제품 설명

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.
