Iris®diaphragm control valve

Energy saving valve for the precise and economical control at low loss of pressure of liquids and gases that can be either clean or contain particles.

Applications

Air for aeration in wastewater treatment plant

Gases

Municipal and industrial wastewater

Slurries and viscous materials

Paper pulp and fibrous suspensions

Pellets with a particle size over 0,5 mm

Sugar suspensions

Drinking water

Features

Highly precise control of the flow rate through concentric Iris® diaphragms (similar to a camera diaphragm).

Energy-saving and low-noise control valve due to its free centric passage.

Maintenance free

Advantages

Energy-saving flow control

No hysteresis

Robust construction, suitable for frequent start-stop

Low pressure losses due to larger open channel

High flow capacity Cv (Kv)

Turbulence-free across the entire range of flow regulation
