Manual Carbon Steel Knife Gate Valve Description

The manual carbon steel knife gate valve works by moving the gate plate perpendicular to the flow direction to shut off the medium, thereby controlling the on/off state of the pipeline fluid. This movement effectively blocks the flow of the medium through the valve, ensuring precise control over the fluid.

With a shorter structural length, the knife gate valve experiences lower flow resistance when the fluid passes through, which contributes to higher flow efficiency and reduces energy loss. This feature is especially beneficial in pipeline systems requiring high flow rates.

Additionally, the manual operation makes this valve widely applicable in situations where simple and reliable control is necessary. Its straightforward design, ease of operation, and low maintenance requirements make it a popular choice in industrial settings, particularly for applications involving particulate matter or wastewater treatment.

Valve Body

a) The knife gate valve adopts an integrated structure with an ultra-thin body and full-bore flow channel. This design effectively minimizes medium leakage, reduces flow loss, lowers costs, and facilitates installation and operation.

b) The bottom of the valve body flow channel has a groove-free design, which prevents medium accumulation and avoids jamming of the gate when closing the valve.

Gate Plate

a) The bottom of the gate plate is designed with a knife-shaped arc, providing a strong shearing effect and excellent sealing performance when the gate plate moves. This makes it especially suitable for controlling dry pulp and fiber-containing media.

b) The thickness of the gate plate can be increased according to actual pipeline pressure requirements.

Valve Seat

a) The U-shaped valve seat achieves sealing by compressing the edges of the gate plate, ensuring 100% bidirectional pressure resistance while reducing friction between the gate plate and the valve seat.

Others

The dual-bearing design significantly reduces the valve’s torque, making opening and closing easier.
