Emerson has expanded its line of Asco miniature 090 Series solenoid valves to include a new 3-way 090 Series valve. This configuration allows for lighter weight solutions with a smaller footprint for gas control in oxygen supply and compression therapy applications, as well as in gas analyzers.
Originally developed as a 2-way valve for air and inert gases in portable medical equipment, the 090 series offers a compact architecture, a small footprint (10.8 millimeters), and a service life of 50 million cycles. These features ensure maximum reliability. The new 3-way configuration of the 090 Series valve allows the same mixing or distribution operation to be provided as by a pair of 2-way valves. This further simplifies the design of small, high-precision gas delivery systems for oxygen and other medical devices for home health care.
Like all 090 Series valves, the new 3-way valve optimizes gas flow with a flow-to-size ratio that is excellent for portable medical devices. Molded from PBT (polybutylene terephthalate) plastic, the valve body features seals made of durable FKM (fluorocarbon) elastomer. The 090 Series actuator combines high reliability with low power consumption, maximizing battery and equipment life. The 090 Series valve is also compliant with all relevant RoHS (Restriction of Hazardous Substances) and CE directives.
"The introduction of the Series 090 3-way miniature solenoid valve provides product designers with greater freedom of choice when developing new valve and manifold solutions for analytical and utility applications," said Sven Richter, vice president of Emerson's analytical and medical business. "Combining products such as the new Asco 090 Series valve with Emerson's Rapidly Engineered Solutions program helps our OEM manufacturers, original equipment manufacturers and customers bring superior products to market faster. At the same time, it can improve internal manufacturing and cost efficiencies, which in turn is critical to long-term competitiveness."
