In recent years, China's hydraulic and pneumatic sealing industry adhere to technological progress, accelerate new product development, and achieved good results, and a number of distinctive high-tech products. Beijing's machine tool servo valve direct-acting, low-noise ratio of Hangzhou Electrical Company Seiko hydraulic relief valve (patented), Ningbo, China was the company's electro-hydraulic proportional pressure flow valve (patent pending), both mechanical and electrical integration of high-tech products, and has been put into mass production, and achieved good economic results. Beijing Howard Group's constant power hydraulic variable displacement piston pump, large displacement piston pump to fill the domestic blank, suitable for supporting metallurgy, forging, mining and other large complete sets of equipment. Co., Ltd. Tianjin special **** pressed three gear pump, with a new structure, small size, high pressure, low noise, advanced performance characteristics. Combination of high performance hydraulic gear pump Yuci Ltd., can be widely used in engineering, metallurgy, mining machinery and other fields. In addition, the company GMG solution vane pump high-pressure high-performance, Ningbo Yonghua high pressure hose assembly company Wuxi Institute of Technology Co., Ltd. for a variety of pneumatic automation equipment for the new WPI series are very unique cylinder new products.

To cope with the new situation after China's accession to WTO, the business of the hydraulic industry to accelerate technological innovation and improve product competitiveness in the market, a number of high-quality products successfully for the state key projects and key supporting host, to achieve better economic and social benefits .

Gas pipeline production line of hydraulic equipment lapping Tianjin Engineering Machinery Co., Ltd. is the transmission equipment of the national natural gas project; Burgmann Sealing Materials HPHT W-type spiral wound gasket, has been successfully used to increase the hydrocracking unit; Dalian Hydraulic Parts Factory and Shanxi Changzhi Hydraulic steering vane pump is in heavy vehicle steering system critical components, the current annual production of the two plants has reached 10 million units; Qingdao Keeper Sealing Seal's new combination of bi-and large-scale anti-mud seal is were FAW Jiefang 9 tons cars and a tractor trailer seals; addition hydrostatic transmission and multi-way valve, hydraulic Huzhou Miguel's versatile slide valve Weihai pneumatic components combined air regulator valve, hydraulic Guizhou Yang Feng's pump stations and hydraulic shift valve, etc., are praised by users.

This shows the status and role in the national economy, such as hydraulic transmission products and national defense construction is very important. Its development determines the mechanical and electrical products to improve performance. It can not only maximize the mechanical and electrical products to meet the necessary conditions to achieve a variety of functions, but also the completion of major projects, the basic guarantee of major technical equipment, it is of major projects and electromechanical products and equipment to ensure reliability. So the development of hydraulic transmission products is to achieve production process automation, industrial automation, especially important means indispensable.

Now the world have paid attention to the development of basic products. In recent years, foreign hydraulic technology due to the widespread application of high-tech achievements, so in terms of the level of basic products, varieties and expanding application areas has greatly improved and developed.

Production of hydraulic products have a certain level of production capacity and technology research system. Especially basic products industry over the past decade to get state support, improved equipment levels, has been able to produce a full range of varieties and specifications of products, has been able to automobiles, engineering machinery, agricultural machinery, machine tools, presses, metallurgy, mining, power generation equipment, petrochemicals, railways, ships, ports, light industry, electronics, medicine and defense industry offers a wide range of basic products. By combining scientific research and research in the proportion of results, and other hydraulic servo systems and components have been used in the production. Encouraging progress has been made in terms of products, such as CAD and CAT, and has been widely used.
