Bidirectional Knife Gate Valve – Series 752, Flanged, Heavy-Duty Slurry Valve

The Series 752 Bidirectional Knife Gate Valve is purpose-built for the harshest industrial environments involving slurry, pulp, abrasive solids, and high-pressure fluids. This valve offers zero-leakage sealing in both flow directions, thanks to its robust dual-seated design with precision-machined metal seat reinforcements.

Its flanged body design allows for easy installation and high mechanical strength, while optional actuation configurations—manual, pneumatic, or hydraulic—make it suitable for a wide range of control systems. The Series 752 is a preferred solution for demanding industries such as mining, power plants, pulp and paper, and wastewater treatment.
