ATOS阿托斯比例阀意大利*    
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比例阀原理：
阀对流量的控制可以分为两种:一种是开关控制:要么全开、要么全关，流量要么zui大、要么zui小，没有中间状态，如普通的电磁直通阀、电磁换向阀、电液换向阀。另一种是连续控制:阀口可以根据需要打开任意一个开度，由此控制通过流量的大小，这类阀有手动控制的，如节流阀，也有电控的，如比例阀、伺服阀。所以使用比例阀或伺服阀的目的就是:以电控方式实现对流量的节流控制（当然经过结构上的改动也可实现压力控制等），既然是节流控制，就必然有能量损失，伺服阀和其它阀不同的是，它的能量损失更大一些，因为它需要一定的流量来维持前置级控制油路的工作。
