The manual knife gate valve features a bidirectional sealing design, offering 100% pressure resistance in both directions with zero leakage. Its unique U-shaped seat design effectively prevents medium accumulation inside the valve cavity, keeping the valve clean and enhancing its reliability and lifespan. Additionally, this design ensures an unrestricted full-bore flow passage, minimizing resistance and maintaining stable flow. The manual knife gate valve is particularly suitable for media such as pulp, chemicals, sludge, slurry, and water, making it widely used across various industries where efficient sealing and fluid control are critical.

| 
 Valve Body  | 
 a) The knife gate valve adopts an integral structure with an ultra-thin body and a full-bore flow passage. This design effectively minimizes medium leakage, reduces flow loss, lowers costs, and facilitates easy installation and operation.  | 
| 
 b) The bottom of the valve passage is designed without grooves, which prevents medium accumulation and avoids jamming during valve closure.  | 
|
| 
 Gate Plate  | 
 a) The bottom of the gate plate features a knife-shaped arc design, which provides strong shearing action and excellent sealing performance when the gate is in motion. It is especially suitable for controlling pulp and media containing fibers.  | 
| 
 b) The thickness of the gate plate can be customized and increased according to the actual pipeline pressure.  | 
|
| 
 Valve Seat  | 
 a) The U-shaped valve seat achieves sealing by edge compression 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 valve torque, making opening and closing smoother and easier.  | 
We can design and develop according to the needs of our customers to meet the requirements of different clients.
