Valve Repair & Testing Equipment

  Portable machines for grinding and lapping of flat sealing surfaces in globe and safety valves, val 

Portable machines, facilitating quick grinding of conical sealing surfaces in 

• High-pressure, shut-off, control and globe valves.
• Standard seat angles of 30° (2×15°), 40° (2×20°), 60° (2×30°), 75° (2×37,5°), 90° (2×45°) (other angles and dimensions on request)

 High-speed precision grinding machines for the machining of a build-up weld, sealing surfaces, conical surfaces and bores in valves, cylinders, pump housings and flanges 

 Portable grinding and lapping machines for the repair of sealing surfaces in gate valves and check valves (non-return valves) and on wedges, disks, and flange

Repair work on wider seats of parallel slide gate valves and wedges as well as check valves and disks.

 Portable machines for high-speed grinding of hard sealing surfaces (≥ 35HRC) in high-pressure gate valves and wedges and check valves and disks of various design.

 Convert drill press or radial arm drill into a precision valve repair center onsite. 

 Stationary ball lapping machine, suitable for finishing the ball and metallic sealing seats of a ball valve so that they fit together perfectly. The machine produces an exact surface shape between the lapped workpieces. 

 Grinding and lapping machine with eccentricity for the machining of sealing surfaces/nozzles in safety valves.

Stationary surface lapping machines, particularly suitable for the lapping of valve disks, axial face seals, and wedges. 

  Stationary grinding and lapping machine for the machining of sealing surfaces in shut-off valves, wedges, safety valves, etc.
