Description
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
