Valvole Fluidoche Proporzionali

Dolphin Fluidics' proportional Smart valves are 2-way, normally closed, full-separation valves for accurate dosing, mixing and dispensing of liquids and gases. The Air/Gas/Vapour Smart valve has two independent channels; channel 1 proportionally controls an air flow, channel 2 proportionally controls vapour or liquid. 

The Smart air/gas/liquid valve has a very low power consumption, up to 20 times lower than conventional solenoid valves, and silent operation, and can be directly interfaced to external pressure, flow or temperature sensors so that it can be closed-loop controlled to the target fluid dynamic function.  Each valve can be easily customised to meet the most stringent functional requirements of different applications, in terms of electronic and mechanical interface, fluidic performance and control electronics and communication on IoT platforms.
