ATOS阿托斯比例閥意大利*    
In May of 2015, Atos SpA assumed full ownership of its North American Master Distributor, Fluid Power Associates Inc. located in York - Pennsylvania, USA. 
With an efficient operation and growing revenues, FPA was acquired by Atos to serve as the company’s North American headquarters and has been renamed “Atos North America”. 
The company has skilled technical staff, advanced testing benches, and an expansive inventory to help continue the steady growth of market share in North America.
With 25 distributors throughout the United States, Canada, and Mexico, the company has a solid foundation for future growth. By continually refining its distributor network and building a strong portfolio of direct business, the target for Atos North America will be $25 million in annual sales in the next five years.

ATOS比例閥原理：
閥對(duì)流量的控制可以分為兩種:一種是開(kāi)關(guān)控制:要么全開(kāi)、要么全關(guān)，流量要么zui大、要么zui小，沒(méi)有中間狀態(tài)，如普通的電磁直通閥、電磁換向閥、電液換向閥。另一種是連續(xù)控制:閥口可以根據(jù)需要打開(kāi)任意一個(gè)開(kāi)度，由此控制通過(guò)流量的大小，這類閥有手動(dòng)控制的，如節(jié)流閥，也有電控的，如比例閥、伺服閥。所以使用比例閥或伺服閥的目的就是:以電控方式實(shí)現(xiàn)對(duì)流量的節(jié)流控制（當(dāng)然經(jīng)過(guò)結(jié)構(gòu)上的改動(dòng)也可實(shí)現(xiàn)壓力控制等），既然是節(jié)流控制，就必然有能量損失，伺服閥和其它閥不同的是，它的能量損失更大一些，因?yàn)樗枰欢ǖ牧髁縼?lái)維持前置級(jí)控制油路的工作。
