उत्पाद का वर्णन
Custom DV Valve Piston for Steam Turbines
Product Overview

The DV valve piston serves as the key reciprocating sliding component within steam turbine DV governing valves. Driven by EH hydraulic oil, it precisely adjusts steam intake volume to stabilize turbine rotation speed and unit load, directly determining the safety and regulation accuracy of power generation equipment.

Our factory specializes in custom manufacturing of DV valve pistons for power equipment manufacturers worldwide, delivering high-precision, long-life mechanical parts that solve frequent wear, sticking, and leakage issues common with original pistons.

Comprehensive Customization Solutions

We customize pistons fully according to customer working conditions, drawings, or physical samples:

  • Structural customization: Outer diameter, central mounting hole, multi-step flange, damping grooves, balance oil passages, sealing shoulder size
  • Material customization: Medium carbon alloy steel, nitriding special steel, corrosion-resistant stainless steel
  • Surface strengthening customization: Ion nitriding, hard chromium plating, mirror polishing, anti-erosion coating
  • Tolerance customization: Meet ultra-high precision sealing standards of high-pressure EH hydraulic systems
Outstanding Product Performance
Smooth Reciprocating Motion

Ultra-fine grinding and mirror superfinishing create extremely low surface roughness. Tight geometric tolerance control ensures consistent clearance between piston and valve sleeve, preventing valve vibration, sticking, and unstable flow adjustment during frequent load fluctuation and unit start-stop cycles.

Superior Wear & Corrosion Resistance

Dense hardened surface layer effectively resists erosion, oxidation, and impurity abrasion from high-temperature EH oil. This significantly reduces maintenance cycles and replacement frequency for power plant units, substantially lowering operational costs.

Precise Linear Flow Control

Symmetrically distributed throttling and balance structures ensure linear hydraulic response. The piston maintains stable regulation accuracy under long-duration variable load operation, improving overall unit efficiency and safety.

Complete Quality Control System
Inspection Stage Quality Checks
