Bürkert’s Twinpower actuator technology

Bürkert Fluid Control Systems has developed an actuator design for solenoid valves that increases the power density by using two coils. Twinpower actuator technology is now available as a complete standard valve line in widths of 10mm and 16mm, with a variety of fluidic and electrical connectionsAn improved membrane seal allows a leakage rate of 10–6mbar*l/min to be achieved. The geometry of all the bodies has also been optimised for improved flushability.In comparison with conventional actuator technology, Twinpower valves are much more compact without loss of power. The intelligent interplay of the two coils increases power density substantially.The design also makes it possible, with reduced width and identical pressure, to double the flow rate of comparable valves with a conventional coil system. Twinpower also enables significant energy savings. There are more than 1,000 possible variants for each width with optimal flexibility in adapting the valves to specific applications. These applications include clinical diagnosis, life science, medical and analysis technology.
