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
