Electro-hydraulic loading gate, abrasion-resistant and frost-proof highway valve
Structural Features and Applications:The palate gate series features a simple structure, easy operation, thorough unloading, long service life, and flexible opening and closing. Made of steel plate welding, it is driven by an electric (hydraulic) push rod, ensuring smooth operation and low failure rate. It can quickly cut off the material flow. Widely used in industries such as construction materials, metallurgy, mining, electricity, chemicals, light industry, and grain, it serves as the unloading control device for various drop material systems.

Pleated gates, also known as pleated valves, jaw valves, pleated discharge valves, electro-hydraulic pleated gates, electric pleated gates, arc valves, pleated ash discharge valves, etc.
The gate valve consists of components such as the main body, sector gate plate, shaft, gears, seals, and actuator. Made by carbon steel welding, it features a unique structure, flexible operation, and reliable performance without jamming. Different transmission devices can meet various operational requirements. Electric gate valves use electric actuators with overload protection to prevent motor burnout, allowing for remote operation or programmable control with adjustable reciprocating travel for position locking. Electro-hydraulic gate valves utilize electro-hydraulic actuators with full hydraulic transmission, enabling variable speed adjustment for both pushing and pulling forces. Pneumatic gate valves use pneumatic actuators, which can be remotely controlled or locally operated through accessory combinations.
Operating Principle
The gate valve employs an electro-hydraulic push rod with full hydraulic transmission, allowing for stepless adjustment of both push and pull forces. The gate is actuated manually or by an actuator, which moves the lever, causing the gears to rotate the sector gate around the axis. This opens the two sector gates to the sides, allowing the material to fall. Once the receiving device is fully loaded, the actuator drives the lever again to reset the sector gate, closing off the falling material.
Usage Instructions
Please note the medium flow direction marked on the gate body when installing the gate. When connecting the flanges, add sealing washers and then tighten the bolts evenly. Additionally, during operation, identify the opening and closing direction of the gate leaf and properly wire the actuator. It is crucial to regularly lubricate all transmission parts during operation to extend the service life of the gate. Improper operation will increase the wear on the gate.
Usage
Pit gates are suitable for bulk density≤2.5t/m³ various ores, coal, coke, slag, chemical products, and other loose materials, widely used for bottom unloading in storage for industries such as building materials, metallurgy, chemicals, and glass.
