Electro-hydraulic flat gates Disadvantages: When the medium pressure is low, the sealing force of the metal sealing surface is not sufficient to achieve a satisfactory seal. On the contrary, when the medium pressure is high, if the sealing surface is not lubricated with system media or external media, frequent opening and closing may cause excessive wear of the sealing surface. Another downside is that a circular gate that moves laterally on a circular flow path is only sensitive to flow control when it is at 50% of the valve closing position. Moreover, when the gate breaks the flow of high-speed and high-density media, it will produce severe vibration. If the valve seat is made into a V-shaped port and tightly guided with the gate, it can also be used as a throttling.
Electro-hydraulic plate gates are widely used in pipelines for controlling dust flow in building materials, metallurgy, and mining industries. They are ideal devices for controlling the flow of dust materials.
Features: Electro-hydraulic flat gate has simple structure, light weight, flexible operation, convenient assembly and disassembly, high quality carbon steel, high strength, good performance and long service life; the use of electro-hydraulic push rod is convenient and fast. To a lesser degree, the intensity of human labor is reduced.
Working principle: The gate is mainly composed of frame, gate, cylinder, power source, etc. The control valve can be controlled by the advance and retreat switches and stop switches on the control box and the reciprocating motion of the gate can be controlled horizontally to achieve the purpose of opening and closing the valve.

main features :
1.Mainly used for sticky soil after grained soil and medium and light soil "to farming rake", "pre-sowing soil", leisure and other operations, the harrow have strong soil performance, high quality work .
2.Wide operation, narrow delivery, easy folding, reliable structure, efficient operation, transport and flexible.
Electro-hydraulic flat gates Advantages: Small flow resistance, non-reduced flow resistance is similar to the short tube flow resistance. The flat gate valve with diversion hole is installed on the pipeline and can be cleaned directly with the pig. Since the gate plate slides on the two valve seat surfaces, the plate gate valve liquid can be applied to a medium with suspended particles and the sealing surface of the plate gate valve is actually positioned automatically. The seat sealing surface is not damaged by the thermal deformation of the valve body. And even if the valve is closed in the cold state, the hot elongation of the stem will not overload the sealing surface. At the same time, when the valve is closed, the plate gate valve without a diversion hole does not require a high accuracy of the closed position of the gate. Therefore, the electric plate valve can use the stroke to control the opening and closing position.
