Project Description


GMA type slurry knife gate valves succeed in carbon industry for several carbon mining plants in Ukraine.

The polyurethane metal cored sleeves offer a bi-directional shutoff of the valve and prevents the fluid to be in contact with the body in the open and close positions.

A revolutionary secondary seal design prevents leakage at the top of the valve at high working pressures and reduce valve maintenance.


  • Bonnet-less knife gate valves.
  • Polyurethane sleeves.
  • Low maintenance.
  • Up to 10bar working pressure.
