Product detail:
As the name suggests, a knife gate valve features a blade-shaped diagonal incision at the bottom of the flat gate plate, which has the function
of cutting off the medium, ensuring that the valve can close without being blocked by the medium. This type of valve is generally used for
opening/closing the flow of media such as pulp, coal ash, chemical raw materials, sewage, and food. The opening/closing component of a
knife gate valve is the gate plate, whose movement direction is perpendicular to the fluid direction. Knife gate valves can only be fully opened
or fully closed, and cannot be used for regulation or throttling. This valve is easy to operate, allows free opening, and features flexible and
reliable movement; the gate plate is simple to assemble and maintain, the sealing structure is reasonable, and the sealing ring is convenient
and practical to replace. The gate plate of the knife gate valve has a shearing function, which can scrape off adhesions on the sealing surface
and automatically remove debris. The stainless steel gate plate can prevent sealing leakage caused by corrosion.

Product features:
1. The valve body adopts an integral design, with low fluid resistance and flexible and convenient operation.
2. The screw drive adopts a double plane bearing design, which greatly reduces the transmission friction and facilitates the opening and closing of the valve.
3. The sealing valve seat of the knife gate valve adopts a movable seal, and an O-ring pre tightening provides pre tightening force to make the sealing valve seat tightly adhere to the valve plate, greatly reducing leakage. It has an automatic compensation function for the wear of the sealing pair in long-term use, improving the service life of the valve.
4. Fixed guide claw, no groove design, not easy to cause medium accumulation and jamming.
5. The valve seat can be selected as a metal hard seal or a soft seal according to the needs of the medium and industry. The gate plate is treated with hard chromium plating or ion nitriding on the surface, making it more wear-resistant and enhancing the service life of the sealing surface; Soft sealing valve seats can be selected from PTFE, NBR, or EPDM, with good sealing performance and corrosion resistance.
