 The hydraulic valve is an integral part of the Fluid Power Transmission functional

unit. On the one hand, the optimization of fluid power systems to upgrade to a hydraulic nut

hyd raulic valve to a corresponding increase in performance; the other hand, the

innovation of the hydraulic valve to the fluid system has brought new vitality.

Today, the hydraulic valve size, performance, energy consumption, intelligence,

manufacturing processes have a great deal of development. With the integration of

hydraulic systems and electronic technology, IT technology and network technology,

hydraulic valve into the digital age.
Technology and market and promote each otherhydraulic manifold block

      Development should be of the hydraulic valve technology and market

integration, it is divided into three levels and three development directions. First

is the technology to occupy the high ground of the market, the high-end market needs

of high-level, high level of technology. At present, general-purpose CAN bus, the

electro-hydraulic bus integration technology will occupy the technical high ground

over the next five years. Major multinational hydraulic company have been or are

being developed based on this technology on the basis of the hydraulic valve series,

and for the variable control of the hydraulic pump, and a variety of valve-regulated

loop. Development in this area, leading to construction machinery hydraulic

products, such as has been used in the hydraulic control of the paver the

multinational Sauer-Danfoss PLUS1 series; Rexroth is also committed to developing

these products and technologies. These multinational companies have been in the

forefront in this regard.hydraulic hose crimping machine

      The second level i s the combination of technology and market. This is a

popular concept in the international market, that is, not just products but to

provide users the solutions they need or the whole idea of ​​selling. This concept

development for hydraulic vendors to provide to the user is a value-added services,

not just the traditional products.

      The third level is the market factors dominated the development of the

hydraulic valve is the improvement of the integration, as well as high-volume, low-

cost mode of production. In this regard, it is worth noting that the cartridge

valves, as one of the five connected hydraulic components, is to increase market

share at a faster rate.

      Future trends in cartridge valves in the extrusion plate valve market space.

Plate valve in the coming years is still th e mainstay of the market, but no longer

has an absolute advantage. Cartridge valves in the future will gradually replace the

plate valve to become the main body of the valve. This is because the cartridge

valves is not just a change in the form of structure, but also original unexpected

impetus to the development of the hydraulic valve. Cartridge valves, construction

machinery hydraulic valve to reduce weight, at the same time, this valve also has a

light weight, low cost, easy to develop highly integrated, easy combination of

knowledge of proprietary and strong, adaptable system changes and other advantages.

So it is not only the development of hydraulic valves, greater plasticity, but also

to the formation of the system to bring more proprietary. In recent years, some

foreign hydraulic system patent is the application of cartridge valves. Pass the
< br />entire flow range of cartridge valves and cartridge valves can be split valve in the

next two, the second pass for more than 300 ~ 500 l / min Cartridge Valves,

cartridge valves for 300 ~ 500 l / min following system areas. Should see the field

of hydraulic forward 42 ~ 48MPa, to be able to achieve this pressure field to the

form of the connection of the valve only Cartridge.

      Digital valve future with proportional valves, servo valves complement the

struggle for a new new valve. It has lower prices and easier to connecting with the

computer, enlarge the drive easier, and smaller features. Typical applications are

already visible on the Sauer-Danfoss PVG proportional multi-way valve, EATON,-

VICHERS the two-pass plug flow valve patented products can be seen. Ho high

Electromechanical Technology Co., Ltd. in 2006 to develop h igh-speed switching

digital valve 31.5MPa under no-load frequency response of 0.2ms following 31.5MPa

under the frequency response of 2ms the following to achieve the best level The

reason to reach this level mainly due to breakthroughs in materials.

      After less than five years of development, our hydraulic industry, has entered

the world. Hydraulic industry should seize the development opportunities of the

reform and opening up, entrepreneurs and technical personnel to update the products

and ideas from the concept of value-added for the user to reflect the sense of

market competition, standing on the peaks and the forefront of the market.
