GEA manufactures two types of butterfly valves: wafer style (02 series) and demountable (03 series), which is assembled via sanitary Tri-Clamps. All valves can be supplied with either pneumatic actuators or manual handles, or with locking pins to fix the valve position.
The valve is used to isolate or regulate flow. The disc is positioned in the center of the pipe and, passing through the disc, is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow; therefore, a pressure drop is always induced in the flow, regardless of valve position.
The “butterfly” is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter of a turn so that it allows almost unrestricted passage. The valve may also be opened incrementally to regulate product flow.Showing 0 of 0
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.
