Product Description

Product Description

Knife Gate Valve

Knife Gate Valves, or simply knife valves, are specialized valves designed to handle thick liquids, fibrous materials like pulp, or gases. They use a thin, blade-shaped gate to control the flow, moving perpendicular to the flow direction. When closed, the two sealing surfaces of the gate create a wedge, enabling a secure shut-off for enhanced control in demanding applications.

Product Parameters

 

Structure and Sealing Options:

• Valve Body: Features a cavity-free design. The gate slides within a side guide groove and presses against the valve seat to create a reliable seal.
• Bidirectional Sealing: The O-shaped valve seat enables bidirectional sealing, with options for rigid or elastic wedge gate to further enhance sealing effectiveness.
• Self-Sealing: Primarily seals with medium pressure, although an external force may be required for forced sealing in some applications.
• Installation: Recommended for vertical pipeline setups.

Product Features

• Control Flexibility: Operable locally or remotely, with options for customizable position display and centralized control.
• Lightweight Design: The carbon steel body is 20%-30% lighter than traditional gate valves, making installation and maintenance more manageable.
• Enhanced Sealing and Efficiency: Optimized for effective pipeline closure, minimizing leakage and boosting production efficiency.
• Material Durability: Sealing surfaces are crafted from wear-resistant, corrosion-resistant ceramic, which extends valve life and improves cost-effectiveness.
