Development History And Brief Introduction Of Hydraulic Screw Cartridge Valve

 

Formation stage (1970-1980): with the establishment of specialized factories such as sun company in the United States in 1970 and the establishment of intergraded hydraulic in Britain in 1972, it marks its formation. Its application can be traced back to the relief valve used in aircraft fuel pump by the US air force. Due to its small size and light-weight, it has been extended to related fields. The world hydraulic industry association was established in various countries in the 1950s and 1960s. Now there are assorted products from the hydraulic industry like hydraulic adapter fittings. We can trace the trace of this kind of valve. But it did not form a climate, it was only used locally.

Development stage (1980-2000): a number of threaded cartridge valve manufacturers have been established, including fluid power systems and delta power.

 

Merger stage (2000-2010): this period set off a round of merger among hydraulic multinational enterprises in the world. In addition to Moog, which mainly produces servo valves, Parker, Bosch Rexroth, Eaton, Sauer Danfoss, etc. have acquired their own professional factories of screw cartridge valves and other products like stainless steel hydraulic ball valves. At present, it is still in the process of integration and integration after the acquisition.

 

In this stage, China's thread cartridge valve enterprises are also brewing new development opportunities. Ningbo Ketai Hydraulic Co., Ltd. has developed with half of the domestic and foreign market performance, especially focusing on the solenoid valve. At present, Taiwan's industrial hose manufacturers are more involved in this field, and other domestic small enterprises are also building one after another. According to the information released to the world, the annual production capacity of hydraforce in China in recent years has reached 6 million, which is equivalent to the output of all hydraulic components in China in 2005. Haihong of China also claims that the annual production of 1 million pieces in recent years.

 

The formation of a screw cartridge valve as well as products like hydraulic rubber hose is a gradual process. So far, there are few technical books about this field, especially in China, and there are few articles published in magazines. The reason is that it is only a structural change on the surface, and there is neither innovation in principle nor breakthrough in performance. Therefore, it does not belong to the category of high-tech, but is a practical technology, so its development has not received high attention. However, after unknown development, it has gradually formed its own systems like hydraulic power transmission system and characteristics in the field of construction machinery, and its influence on the development of hydraulic ball valves has gradually strengthened. Some of its advantages have been developed and become a kind of valve such as a 3 way stainless ball valve. Since it has formed one of the mainstream, it has formed a qualitative change from a quantitative change. At the beginning of the 21st century, many famous hydraulic multinational enterprises for example stainless steel ball valve suppliers have acquired the influential or characteristic screw cartridge valve enterprises or companies in the hydraulic field of the world, and brought them into their own business field, and formed a kind of acquisition trend, which shows this point. It is also proved that this kind of valve-like a stainless ball valve will have further development vitality.

 

Despite the rapid development of China's hydraulic industry for instance hydraulic rubber hose manufacturers, the technology, especially the innovation technology, is relatively backward and weak, so is the screw cartridge valve technology. Up to now, there are already 2-3 domestic thread cartridge valve enterprises famous, and their international influence is just beginning. I dare say that Jazzy is one of the famous companies as it has a lot of products like hydraulic quick release coupling that is advanced and popular in the field.
