Check valves, they close as soon as the flow is interrupted or the flow direction is reversed.
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.

The impact of global warming is increasingly apparent all over the world. Towns and cities everywhere face the same challenge: providing their communities with reliable, affordable, sustainably sourced heat. GEA spoke with an expert in the field, Kenneth Hoffmann, Manager, Heat Pumps at GEA Heating & Refrigeration Technologies, about tackling global warming faster.
Something caught Farmer Tom's eye. Instead of another product demo, GEA showcased innovations via AR. That's only the start of GEA's interactive digital farm.
GEA scientists are working with researchers at the Graz University of Technology to configure a homogenization process and technology that turns eucalyptus pulp into 3D-printed, organic structures mimicking human veins, arteries and other tissues.
