Portable bench for repairing of valve sealing surfaces

Portable benches for repairing of sealing surfaces of gate valve housings
without removing them from pipelines and gate valves wedges.

High quality of the machined surface is achieved due to the design of the
machining head and making corrections, which create a complex planeparallel
movement of the tool along the processed surface.

Achievable fl atness up to 1 μm, roughness up to 0.08 microns (10..12 class).

Construction

■ fi xing device for mounting on the middle fl ange

■ pneumatic/electric drive

■ interchangeable machining heads for grinding and lapping

■ setting device for processing wedges

Equipment

■ carrying case

■ device for processing wedges

■ installation devices

■ pneumatic/electric drive
