■ Product Description

Knife Gate Valve is a high-performance industrial valve, specially designed for medium containing solid particles, such as slurry, sewage, pulp, and ash. Its unique knife-shaped gate can easily cut through viscous and abrasive media, ensuring tight sealing and stable operation even in harsh working conditions.

Also known as slurry gate valve or knife valve, it features a sharp-edged gate that descends into the flow path, effectively cutting through media like slurry, pulp, sewage, ash, and mud to prevent clogging and ensure reliable flow control.

★ Product Features

High Efficiency for Abrasive Media: Precision-machined knife gate ensures smooth penetration into viscous media, minimizing resistance.
Diverse Sealing Options: Soft seal (NBR, EPDM, PTFE) for chemical resistance; Hard seal (Stainless steel, Ceramic) for high-abrasion conditions.
Reliable Operation Modes: Options for Manual (handwheel), Pneumatic, or Electric actuators for automated control.
Space-Saving Design: Wafer and Lug type connections allow for short structure and light weight installation.
Corrosion & Wear Resistance: High-quality materials (Cast Iron, WCB, 304/316 Stainless Steel) adapt to various industrial environments.
