Product Introduction: The knife gate valve, also known as a manual knife gate valve, is a type of gate valve where the gate and seat maintain tight contact for sealing. Its principle involves a circular opening on the gate that matches the pipe diameter, allowing the gate to fully separate or align with the opening during operation. The advantages of this valve include a groove-free valve body that prevents media blockage, full-bore flow characteristics, and sealing structures that can be either soft or hard. The through-conduit knife gate valve features precise construction, excellent craftsmanship, and a compact design. The movable sealing seat is designed with anti-wear and automatic compensation functions, ensuring a longer service life. During opening and closing, the seat and gate move in close contact, providing stable operating force and effective media cutoff.

This valve is widely used in industries such as building materials, metallurgy, mining, and cement for controlling the flow of dusty materials in pipelines. Made from high-quality carbon steel, it offers high strength, reliable performance, and a long service life. The screw and nut are equipped with a soft protective cover to prevent contamination from external dust.

The valve primarily consists of a frame, screw nut, handwheel or electric actuator, sprocket, and gate assembly. Rotating the handwheel drives the screw nut and gate to move horizontally, achieving the opening and closing of the valve.

It features a simple structure, light weight, easy operation, and convenient installation and disassembly.
