Product Description

Product Description

Knife gate valves are engineered to manage viscous liquids, fibrous substances such as pulp, and gases with precision. These valves feature a distinctive blade-like gate that regulates the flow by moving in a direction perpendicular to the flow path. When the gate is closed, its two sealing surfaces converge to form a tight wedge, which guarantees an efficient and reliable shut-off. This design is particularly advantageous for applications where a high degree of control over the flow and a positive shutoff are required, making knife gate valves an ideal choice for industries dealing with challenging fluid dynamics.
 

• Sealing Options: Uses an O-shaped valve seat for bidirectional sealing; wedge gate can be rigid or elastic for improved sealing performance.
• Self-Sealing: Typically seals with medium pressure; external force may be required for forced sealing.
• Installation: Recommended for vertical pipeline installation.
