Zhejiang Stainless Steel Knife Gate Valve Wholesale

Mirror stainless steel knife gate valveWith a high-precision polished stainless steel valve body as the core and a blade shaped gate design, a streamlined structure is formed. The surface of its valve body has undergone mirror treatment, with a smooth finishtallCan effectively reduce medium adhesion and residue; The knife shaped gate adopts a sharp blade design with cutting function, which can easily cut complex media such as slurry, fibers, particles, etc. The valve supports manual, pneumatic or electric drive, and its structural forms include concealed stem, clamp type, etc., to meet different working conditions. The sealing surface material can be selected from hard alloy, tetrafluoroethylene, or rubber to adapt to various media characteristics.

Performance Characteristics

Strong corrosion resistance: The combination of stainless steel material and mirror treatment process endows the valve with excellent acid, alkali, and salt corrosion resistance, making it suitable for harsh environments such as chemical and marine industries.

Reliable sealing: The knife shaped gate and valve seat are sealed in both directions through hard alloy or soft sealing materials. The self grinding effect can compensate for the wear of the sealing surface and maintain zero leakage even after long-term use.

Outstanding cutting function: The blade of the gate can cut off fibers and particles in the medium, preventing blockage, especially suitable for controlling fluids containing solid impurities.

Low flow resistance: The full bore design ensures extremely low resistance when fluid passes through, reducing energy loss and improving system efficiency.

Easy maintenance: The modular structure supports quick replacement of seals or gate plates, without the need to disassemble the entire valve, reducing downtime and maintenance costs.

working principle

Mirror stainless steel knife gate valveBy using a driving device (manual, pneumatic, or electric) to rotate the rotating shaft, the knife shaped gate plate moves linearly inside the valve body. When opened, the gate is lifted to the upper part of the valve chamber, and the medium flows through the channels on both sides of the gate; When closed, the gate descends to the valve seat, cutting off the flow of the medium through the cutting edge, and relying on the pressure of the medium or external force (such as a spring) to press the sealing surface, achieving bidirectional sealing. Some models adopt a self sealing design, utilizing medium pressure to enhance the sealing effect and reduce the risk of leakage.
