Knife Gate Valve
Reliable isolation for slurries, fibrous pulps and abrasive fluids. Supplied and supported in New Zealand by HD Process.
Knife gate valves provide on-off isolation where wedge gates or butterfly valves struggle. A thin, sharpened gate cuts through solids and closes tight, making them ideal for wastewater, mining, pulp and paper, food waste and bio-process slurries in NZ plants.
