Bi-directional sealing
No groove or cavity in the bore of the knife gate valve where slurry can collect
Fully moulded and reinforced body seal. The rigidity of the seal prevents creep of the seal when the knife gate valve is opened or closed, reducing the torque to open and close the valve.
Precision machining of the stuffing box cavity that reduces the force required to seal the knife gate valve which reduces the opening and closing torques
Arched PTFE scrapers across the width of the blade
16 bar pressure rating for valves from DN50 to DN 200 and 10 bar for valves from DN 250 to DN 600
Full bore unrestricted flow
Self-cleaning flush-out corners that prevent deposit build-up in the sealing area
