Knife Gate Valve is specifically engineered for demanding industrial applications involving slurry, pulp, powder, and wastewater. Its compact structure and sharp-edged gate allow it to cut through thick or solid-laden media, making it ideal for industries such as mining, paper, chemical processing, and sewage treatment.
This knife gate valve features a one-piece body, corrosion-resistant coating, and a stainless steel or alloy blade for long-lasting durability. Its unidirectional shut-off design minimizes pressure loss while ensuring a tight seal, even under tough flow conditions. The non-clogging structure and low operating torque make it highly suitable for systems with limited maintenance access.
Available with various actuation options—manual handwheel, pneumatic, or electric—the knife gate valve can be adapted for both remote control and manual operation. It supports installation between flanges using wafer or lug-type connections, depending on system requirements.
As a trusted valve manufacturer in China, we produce all knife gate valves according to international standards such as DIN, and ISO. They are pressure-tested and inspected before shipment to ensure performance and reliability.
Choose our knife gate valve to ensure smooth, safe, and efficient flow control in harsh industrial environments. It’s a reliable solution for handling abrasive and viscous media with ease.
