Portable Valve Grinding Machines
Metals Kingdom Industry Limited supplies portable valve grinding machines for on-site and workshop maintenance of industrial valves. Our manufacturing experience in valve and pipeline maintenance equipment dates back to 1994.
Portable valve grinding machines allow valve sealing surfaces to be repaired without relying entirely on large stationary equipment. Depending on the valve structure and machine model, they can be used for grinding gate valve seats, gate valve discs, flat valve seats, conical valve seats, and safety valve seats.
Portable Grinding Solutions for Different Valve Types
Our portable valve grinding machines are divided into two main product groups:
For Gate Valves
This series is designed for the maintenance of gate valve seats and gate valve discs. Different models use dedicated supports, grinding heads, or adjustable grinding discs to cover their confirmed working ranges.
M-200
M-300C
M-600
MZ-150
MZ-250
MZ-900
MZ-1200
For Globe & Safety Valves
This series is designed for flat valve seats, conical valve seats, safety valve seats, and other applicable sealing surfaces. The correct model depends on the actual sealing-surface diameter, valve structure, grinding depth, and available installation space.
M-100
M-100A
M-100C
MJ-250
MJ-400

How to Select the Correct Machine
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
Required grinding depth
Minimum available installation space
Valve drawings or clear photos
Power-supply requirements
Our team will review the application and recommend a suitable machine, tooling configuration, and accessories according to the confirmed working conditions.
Industrial Applications
Portable valve grinding machines are used in power generation, petroleum and petrochemical processing, natural-gas transmission, nuclear power, offshore engineering, shipbuilding, metallurgy, boiler manufacturing, pressure-vessel fabrication, water treatment, and general industrial maintenance.
