概要
GEA check valves are open autonomously by the pressure which is exerted by the working medium upon the valve disc. They start to open at a differential pressure of 0.01 to 0.05 bar and are fully open between 0.1 and 0.2 bar. As soon as the flow is interrupted or the flow direction is reversed, the valve closes automatically. A built-in damping device makes this type of valve especially suitable in cases where capacity requirements fluctuate. GEA check valves are designed for installation in in industrial heating and refrigeration systems. They are installed on the pressure or suction side of compressors or in pipes in which only one direction of flow is intended.

GEA製品販売部長のパトリック・シュールマンにとって、レシチンは特別な存在です。当初は食用油の精製において脇役にすぎなかったものの、何にでも使える物質として、競争が激しく利益率の低い食用油精製市場で見事に主役の座を獲得。実はこれ、シュールマンが同僚と一緒に開発した、革新的で省エネな新製法によるところが大きいのです。
