 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.

Pleated gates are composed of the main body, wing-shaped gate plate, shaft, gears, seals, and actuating mechanism. Fabricated using carbon steel welding, the structure Operation is flexible and reliable with no jamming. Different transmission devices can meet various working conditions. Electric gate valves are equipped with electric actuators featuring overload protection to prevent motor burnout. They can be remotely controlled or programmed, and the reciprocating stroke can be adjusted for position locking. Electro-hydraulic gate valves use electro-hydraulic actuators with full hydraulic transmission, allowing for variable speed adjustment of both thrust and pull force. Pneumatic gate valves use pneumatic actuators and can be remotely or locally controlled through component assembly.

Working Principle

 The palatal gate is equipped with an electro-hydraulic push rod, featuring full hydraulic transmission with infinite speed adjustment for both pushing and pulling forces. The gate is operated manually or by an actuator that pushes the lever, causing the gears to rotate the sector gate around the axis, opening the two sector gates to the sides, allowing the material to fall. Once the receiving device is fully loaded, the actuator then moves the lever 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 evenly tighten the bolts. Secondly, during operation, identify the opening and closing direction of the gate plate and correctly wire the actuator. Even during operation...  Regularly apply lubricant to all transmission parts to extend the lifespan of the lab valve. Improper operation will increase the wear of the lab valve.

Usage

 Pit gates are suitable for bulk density≤2.5t/m³ of various ore, coal, coke, slag, chemical products, etc., in bulk form, widely used for bottom unloading in warehouses for construction materials, metallurgy, chemical industry, glass, and other industries.
