Diaphragm control valve
DN 25 - 400, 6 bar | IRIS series
Emile Egger & Co. AG
Designed for continuous operation, suitable for various duties. Simple installation and commissioning.
Hysteresis-free and excellent regulation characteristics:
are prerequisites for regulating tasks. This is achieved by the continuously variable aperture from 0 – 100%, similar to the IRIS diaphragm of a camera, always maintaining a central flow and by an enhanced segment edge design.
Non-clogging due to the free, central flow design and the automatic, self-cleaning feature of the segment edges during valve operation. Flushing connections are provided.
Examples of applications:
Air, sugar, suspensions, sewage, sludge, paper stock, drinking water, etc.
Energy cost savings and low noise emission through enhanced design. Fixed throttling apertures and imprecise regulating methods cause unnecessary pressure losses and energy costs. Due to the almost free passage and low turbulences in our valve these are reduced to a minimum. Because of an advantageous basic characteristic, we can operate in an energy saving manner, i.e. with optimal valve apertures.
