Valves that open and close the pipe by rotating the closing device horizontally in relation to the flow direction.
AK Butterfly Valves
GEA butterfly Valves are suitable for installation in the refrigerant cycles of industrial refrigeration systems. The closing device is a disc that opens and closes the pipe by horizontal rotation in relation to the flow direction. The 90° rotation is exerted via the shaft and is either by a hand-operated lever or by electric or pneumatic actuators.
