Energy saving valve for the precise and economical control at low loss ofpressure 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. Please describe to us your requirements with a description of the fluid to be pumped.
