Heavy-Duty Manual Knife Gate Valve for Slurry and Solid-Liquid Flow Applications
The PFZ73 Manual Knife Gate Valve is a high-performance valve designed for reliable shut-off and flow control in pipelines carrying suspended solids, slurry, and fiber-rich fluids. With a nominal diameter range of 50mm to 2000mm and pressure ratings from 0.6 MPa to 2.5 MPa, this valve is ideally suited for tough industrial applications such as pulp and paper, mining, wastewater treatment, power plants, and chemical processing.
This valve features a manually operated, sharp-edged gate that can cut through thick fluids and particulate matter, offering excellent performance in systems where conventional valves may clog or fail. The PFZ73 is capable of handling temperatures from -29°C to 120°C, making it adaptable to a wide range of working conditions.
Manual operation for simple and cost-effective control.
Knife-edge gate design allows for easy passage of viscous, slurry, or solid-laden media.
Compact body with full-bore flow path, reducing pressure drop and flow turbulence.
Flange or wafer-type connection, adaptable to various pipeline setups.
Body materials available in cast iron, ductile iron, stainless steel, or other alloys for corrosion and abrasion resistance.
Optional sealing structures (soft seal or metal seal) depending on medium and pressure requirements.
Pulp and paper slurry
Sewage and wastewater
Coal slurry and ash water
Industrial mud and sediment-laden liquids
The PFZ73 Knife Gate Valve offers outstanding reliability, minimal maintenance, and long service life in challenging environments where flow contains high concentrations of fiber, sediment, or solid matter. Its design ensures tight shut-off, easy manual operation, and reduced risk of jamming or clogging.
Whether installed in paper mills, wastewater treatment plants, or mining tailings systems, the PFZ73 is a trusted solution for harsh solid-liquid flow applications.
