Product Detail

The Didtek Industrial Double-acting Pneumatic Knife Gate Valve is the ultimate solution for handling abrasive, viscous, or fiber-laden media. Featuring a unique beveled knife-edge gate, it easily cuts through solids, fibers, and thick slurries to ensure a tight seal in demanding transport systems. Integrated with a high-performance double-acting pneumatic actuator, the valve provides rapid and reliable automated operation powered by air pressure in both directions. Its slim profile and minimal flow resistance make it an essential component for process automation in mining, pulp and paper, and wastewater treatment industries.

Design Description

Powerful Cutting Blade: The stainless steel gate features a beveled edge that shears through fibers, wood pulp, or debris in wastewater during the closing cycle.
Double-acting Automation: Driven by a dual-action pneumatic cylinder, both opening and closing strokes are air-powered, offering faster response and smoother operation compared to manual or spring-return valves.
Compact Slim Profile: The short face-to-face (Wafer/Lug) design saves installation space and reduces the overall weight load on the piping system.
Abrasion-Resistant Seating: Available with high-performance resilient or metal-to-metal seats, providing excellent erosion resistance and preventing seat clogging or buildup.
Automation Ready: Standardized mounting pads allow for easy integration of solenoid valves, limit switches, positioners, and FRL units for seamless PLC/DCS integration.
