Improve Sealing Performance & Reduce Manufacturing and Maintenance Costs
Double eccentric valves (double offset butterfly valves) are widely used in oil & gas, chemical processing, power generation, and water treatment systems. However, under harsh conditions such as abrasion, corrosion, and high-pressure flow, valve sealing surfaces often suffer from wear, leakage, and reduced service life.
Laser Cladding (Laser Hardfacing) offers valve manufacturers a high-performance solution to enhance durability, restore sealing surfaces, and significantly reduce maintenance and replacement costs.
Why Valve Manufacturers Choose Laser Cladding
Traditional welding or repair methods often cause excessive heat input, distortion, and poor coating adhesion. In contrast, laser cladding technology provides a precise, low-heat-input process that forms a dense, metallurgically bonded coating.
For manufacturers, this means:
• More reliable sealing performance
• Lower rejection and warranty rates
• Extended valve service life
• Higher product value and competitiveness
Key Applications in Double Eccentric Valves
Laser cladding is ideal for repairing and enhancing critical valve components, including:
• Valve disc sealing surface
• Valve seat sealing area
• Erosion and wear-prone zones
• Damaged or corroded surfaces
By applying customized alloy powders (nickel-based, cobalt-based, carbide-reinforced), the coating can be tailored for wear resistance, corrosion resistance, and cavitation resistance, depending on the operating environment.
Core Benefits of Laser Cladding
Laser cladding is not just a repair method—it is a performance upgrade for industrial valves.
• High hardness and wear resistance (Hardfacing)
• Excellent corrosion protection
• Strong metallurgical bonding (no peeling)
• Minimal heat-affected zone (no distortion)
• Precise dimensional restoration for sealing accuracy
This makes it especially suitable for high-precision sealing applications like double eccentric valves.
