Valve Plasma Spray Machine
Automatic plasma spray welding and plasma hardfacing equipment for valve repair, shaft surfacing, pipe part cladding, disk part repair, wear-resistant layer deposition and precision surface rebuilding.
Automatic Plasma Spray Welding for Valve and Rotary Parts
The HALDEN Valve Plasma Spray Machine is designed for plasma spray welding repair and surface strengthening of valves, shafts, pipe parts, disk parts and other rotary components. It is suitable for depositing wear-resistant, corrosion-resistant or repair layers on outer cylindrical surfaces, inner holes, end faces and damaged working surfaces.
The system combines plasma power source, welding operator, displacement machine, precision spindle rotation, linear motion mechanism, arc voltage tracking, welding oscillation and PLC control to support stable automatic plasma hardfacing production.
HALDEN can configure the machine according to component size, coating material, welding method, required layer thickness, production capacity and repair application.

Why Use Plasma Spray Welding for Valve Repair?
Controlled Deposition
Plasma hardfacing supports stable heat input and controlled coating formation on precision surfaces.
Wear and Corrosion Protection
Suitable alloy powders can improve sealing surface performance against wear, corrosion and high-temperature service.
Repair Instead of Replacement
High-value valves and rotary components can be rebuilt instead of replaced, reducing maintenance cost.
Automation-Friendly
Rotary motion, torch travel, oscillation and control systems can be integrated into repeatable production programs.
Industries and Working Conditions
Valve plasma spray machines are used where critical components require surface rebuilding, anti-wear protection, sealing surface repair or corrosion-resistant hardfacing.
