New Actuator for Solenoid Valves Now Offered by Bürkert Fluid Control Systems
Irvine, Calif.-based Bürkert Fluid Control Systems has developed a new actuator design for solenoid valves that increases power density via the use of two coils. The compact technology is now available as a complete standard valve line in widths of 10 mm and 16 mm. The enhanced TwinPower valves, so named for the new double coil feature, are available in the body materials PEEK (polyetheretherketone) and PPS (polyphenylene sulfide) as well as the seal materials FFKM, FKM (American Society for Testing and Materials designations for fluoroeastomers) and EPDM (ethylene propylene diene monomer rubber). For each valve type there are more than 1,000 different variants in the widths 10 mm and 16 mm with different fluidic and electrical connections, such as hose connections, flanged versions and UNF (unified fine thread) threaded connections. According to the company, each single component in the valves was analyzed critically during development of the TwinPower series to identify potentials for optimization.
By improving the membrane seal, for example, it was possible to achieve a reported leakage rate of 10-6mbar*l/min. In addition, the geometry of all the bodies was designed for improved flushability. The intelligent interplay of the two coils increases the power density substantially. In comparison with conventional actuator solutions, the TwinPower valves are much more compact without loss of power. This design makes it possible, with reduced width and identical pressure, to double the flow rate of comparable valves with a conventional coil system. In addition to the high power density, the TwinPower technology also reportedly enables significant energy savings. TwinPower valves are equipped with hit-and-hold electronics as a standard feature, which reduces the energy consumption by 75 percent within 100 ms after switching.
