Model 72 Valve Repair Weld Head

The Model 72 is designed for welding, rewelding, or cladding eroded valve-to-pipe welds or for internal repair of many valve types from 8” through 24” (203 mm - 609 mm). Its modular features allow access through the bonnet without cutting or removal of valve welds. The head design allows installation where radial and axial access clearance to the valve is restricted.

Recommended for use on ID weld repairs, inlay applications along the bore or seat hard-facing and cladding.
