Bidirectional Knife Gate Valve Slurry Valve

Designed specifically for tough industrial applications involving slurry, pulp, powder, and wastewater, the Knife Gate Valve features a compact structure and a sharp-edged gate that can slice through thick or solids-laden media. This makes it well suited for sectors such as mining, paper, chemical processing, and sewage treatment.

Built with a one-piece body, a corrosion-resistant coating, and a blade made of stainless steel or alloy, this knife gate valve is engineered for long‑term durability. Its unidirectional shut‑off design minimizes pressure loss while maintaining a reliable seal, even under demanding flow conditions. The non‑clogging construction and low operating torque make it an excellent choice for systems where maintenance access is limited.

A range of actuation options is available—including manual handwheel, pneumatic, and electric—allowing the valve to be configured for either remote or manual operation. It supports flange mounting using wafer or lug‑type connections, depending on system requirements.

As a trusted valve manufacturer in China, we produce all knife gate valves in accordance with international standards such as DIN and ISO. Each valve is pressure‑tested and inspected before shipment to ensure performance and reliability.

Choose our knife gate valve to achieve smooth, safe, and efficient flow control in harsh industrial environments. It provides a dependable solution for handling abrasive and viscous media with ease.
