 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 flap gate is composed of components such as the main body, sector gate plate, shaft, gears, seals, and actuator. It is made by welding carbon steel and features a structural design. Operation is flexible and reliable with no jamming issues. Different transmission devices can meet various working conditions. Electric gate valves are equipped with electric actuators featuring overload protection to prevent motor burnout, allowing for remote operation or programmable control, and the reciprocating stroke can be adjusted for position locking. Electro-hydraulic gate valves use electro-hydraulic actuators with full hydraulic transmission, enabling stepless speed adjustment for both pushing and pulling forces. Pneumatic gate valves use pneumatic actuators, which can be remotely controlled or locally operated through component assembly.

Working Principle

 The palatal gate utilizes an electro-hydraulic push rod, featuring full hydraulic transmission with variable speed control for both thrust and pull forces. The gate is manually or mechanically operated by pushing the lever, which drives the gears to rotate the sector gate around the axis, allowing the two sector gates to open to the sides, causing the material to fall. Once the receiving device is fully loaded, the mechanism drives the lever again to reset the sector gate, closing off the falling material.

Usage Instructions

Pleated gate valves, please note the medium flow direction marked on the valve body during installation. When connecting the flanges, add sealing washers and then tighten the bolts evenly. Secondly, during operation, identify the switch direction of the butterfly gate plates and properly wire the actuator. That is, during operation...  Regularly apply lubricant to all transmission parts to extend the lifespan of the labial valve. Improper operation will increase the wear on the labial valve.

Usage

 Purse gate valves are suitable for bulk density≤2.5t/m³ various ores, coal, coke, slag, chemical products, and other loose materials, widely used in the bottom unloading of storage for construction materials, metallurgy, chemicals, glass, and other industries.
