Model Selection Guide
The nominal valve size alone is not sufficient for accurate machine selection. Please provide the following information:
Valve type
Nominal valve size
Actual sealing-surface diameter
Flat or conical sealing-surface structure
Valve-seat or valve-disc application
Conical seat angle, where applicable
Required grinding depth
Minimum available installation space
Valve drawings or clear photos
Power-supply requirements
Our team will review the valve structure and working conditions and recommend the suitable machine model, tooling configuration, and accessories.
Industrial Applications
These machines are used in power generation, petroleum and petrochemical processing, natural-gas transmission, chemical processing, metallurgy, shipbuilding, boiler maintenance, pressure-vessel maintenance, water treatment, and general industrial maintenance.
