Product Description:
The knife gate valve is a unidirectional control valve commonly used in industrial pipelines for on-off operations. Its unique design prevents clogging when handling media with particles, ensuring smooth operation. The beveled knife edge generates high shear stress, allowing for easy flow penetration and reliable sealing.
Key Features:
BODY:
• Cast-in guide claws at the bottom of the port securely hold the gate in place, preventing clogging and ensuring a tight seal.
• Integral body design ensures easy assembly and zero shell leakage.
• Full port design minimizes pressure drop and maximizes flow capacity.
• PTFE resilient seats prevent metal-to-metal contact between the gate and body.
GATE:
• Beveled knife edge provides strong cutting force and excellent sealing performance.
• Gate thickness can be increased to handle higher pressure conditions.
• Both sides of the gate are polished for better sealing and reduced jamming.
• Hard chrome coating enhances durability for metal-sealed applications.
SEAT:
• Side-entry seat is replaceable, reducing maintenance costs.
• L-shaped seat retainer locks the seat securely and protects it from direct flow erosion.
