YTO rough terrain forklift,cartridge discussed in the electro-hydraulic control valve stent hydraulics

systems application basis and prospects, proposed design, analysis of the works. Cartridge think large flow capacity, fast response, the use of electro-hydraulic pilot control, particularly suited to this kind of stand conditions, in line with technology trends, it is worth promoting. An application based on analysis Shift low frame rate has become an important factor in fully mechanized mining production. To accelerate the shift frame rate, stand in the hydraulic system used in cartridge valves. Cartridge direction solenoid valve is also used as a pilot valve, the main valve (poppet) were pilot control, electro-hydraulic control principle is equivalent to the control valve, but the through-flow capacity of the cartridge valve (up to 10000L / min or more) large , fast response, reliable operation and other advantages, the tubular valve unmatched, making it more suitable for use in electro-hydraulic control system of the holder, without the need to develop a dedicated pilot control using electromagnetic large flow of the main valve, both meet the requirements, but also to improve performance, improve the general level, to solve the problems caused by the tubular valve inherent defects arising from the fundamental.
