Egger iris diaphragm control valve

Product description

Energy-saving valve for the precise and economical control at low pressure drop of liquids and gases that are clean or contain particles.

Egger Iris® diaphragm control valves are characterized by a flow that is always centered. The aperture can be varied continuously, similar to a camera aperture. This allows constant flow rates to be reproduced in any position.
