Vatac has recently introduced a new member to its valve products, the slurry knife gate valve, which is also called sleeve type knife gate or rubber lined knife gate valve. Some of the features of the slurry knife gate valve include: 100% Isolation; bubble-tight shut-off results in absolutely zero downstream leakage, Double-seated design provides bidirectional flow and shut-off. Unobstructed flow eliminates turbulence minimizes pressure drop across valve. No seat cavity where solids can collect and prevent full gate closure. Dynamic self-adjusting secondary seal. No gate or stem packing is required, eliminating packing leakage and maintenance. No metal parts in contact with the flowing slurry. Adaptable frame (yoke) design features a top-removal stem nut. It can be field modified to an air cylinder or bevel gear in the field without welding. Open-Closed lockout brackets standard through 16″. It is ready for optional factory supplied or customer supplied lockout pins.
General applications for the slurry knife valve include Mining, Power, Pulp and paper, Phosphates, Steel/Metals and Cement industries. Its size ranges from 2″ to 24″. Temperatures standard sleeve rated to 180°F. up to 300°F with optional or rubber lined knife gate valve.
