Electric knife gate valve, manual knife gate valve, electric stainless steel gate valve. The manual knife gate valve, also known as the manual knife gate valve, is a type of valve where the gate and the seat are always in close contact for sealing. Its principle involves a circular opening on the gate that matches the diameter of the pipe. The opening and closing of the gate allow the circular opening to completely separate from or align with the pipe diameter. The manual knife gate valve is a primary control device widely used in metallurgy, mining, building materials, and grain industries.The manual knife gate valve is typically used for controlling the flow or conveying capacity of powdered materials, crystalline materials, granular materials, and small lump materials in conjunction with dischargers. The diameter of the manual screw gate valve matches the feed port of the discharger and is available in both square and round shapes.

The manual knife gate valve is often used in conjunction with discharge devices or silos. The manual screw gate valve is easy to install with flange connections and is available in both square and round inlet and outlet shapes. It comes in dozens of specifications based on the diameter and is widely used in industries such as metallurgy, carbon, chemicals, and building materials. The manual knife gate valve features a simple and compact structure, reasonable design, reliable sealing, light and flexible operation, small size, smooth flow path, low resistance, easy installation, and easy disassembly. The manual screw gate valve can be installed horizontally or vertically and offers features such as wear resistance, automatic compensation, and long service life. During normal use, all transmission parts of the manual knife gate valve should be regularly inspected and lubricated for maintenance.

1. Before installing the gate valve, check the valve cavity and sealing surfaces to ensure no dirt or sand particles are attached; 2. The bolts at each connection point must be tightened evenly; 3. Check the packing area to ensure it is tightly pressed, guaranteeing both the sealing of the packing and the flexible opening of the gate; 4. Before installing the valve, users must verify the valve model, connection dimensions, and pay attention to the flow direction of the medium to ensure compatibility with the valve requirements;
