Huayan’s BWG multi‑axis CNC welding machines serve as the core platform for valve component overlay tasks. Combined with CZ‑PAW plasma cladding and CZ‑LASER laser cladding systems, they perform high‑quality hard‑facing for gate seats, disc plates and triple‑offset butterfly valve sealing surfaces.

These systems work with Stellite, 507Mo, nickel‑base and other overlay alloys. Equipped with automatic surface detection and no‑teaching programming function, the equipment keeps low dilution rate and uniform overlay thickness. It helps valve producers reduce rework rate and satisfy strict requirements for high‑pressure & high‑temperature valve service conditions.
