Description The AUTOFLOW® devices are automatic flow rate stabilizers capable of maintaining a constant flow rate of the medium as the operating conditions of the hydraulic system change. They are used to automatically balance the hydraulic system, guaranteeing the design flow rate to each terminal. This series of devices is fitted with an interchangeable flow rate regulator, made of high resistance, scale resistant and low noise polymer, for specific use in air-conditioning, hydraulic and domestic water systems. This special AUTOFLOW® series is also supplied with a compact, reduced size valve body for easy installation on individual terminals or system zones.
