Portable Valve Grinding Machines for Gate Valves
Metals Kingdom Industry Limited supplies portable valve grinding machines for on-site and workshop maintenance of gate valve sealing surfaces. Our manufacturing experience in valve and pipeline maintenance equipment dates back to 1994.
This product series is designed for grinding gate valve seats and gate valve discs. Different models cover small, medium, large, and extra-large valve applications. The correct machine should be selected according to the actual sealing-surface diameter, valve opening, required grinding depth, installation space, and site conditions.

How to Select the Correct Model
Valve nominal size alone is not sufficient for accurate machine selection. Please provide the following information:
Valve type and nominal size
Actual sealing-surface diameter
Valve-seat and valve-disc dimensions
Minimum spacing between the sealing surfaces
Required grinding depth
Available installation and operating space
Power-supply requirements
Valve drawings or clear photos
Our team will review the actual valve 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, metallurgy, shipbuilding, papermaking, boiler manufacturing, pressure-vessel production, water treatment, and general industrial maintenance.
