Emerson has expanded its ASCO Series 090 line of miniature solenoid valves, adding a new three-way Series 090 valve configuration to enable lighter, more space-efficient solutions for gas control in oxygen therapy, compression therapy and gas analyzer devices.

Originally developed as a two-way valve for air and inert gases in portable medical devices, the Series 090 valve features a compact architecture, small (10.8 millimeter) footprint and 50 million cycle life.

Like all Series 090 valves, the new three-way valve is built to maximize gas flow, with a flow-to-size ratio that is well suited to portable medical device applications. The valve body is molded from polybutylene terephthalate (PBT) plastic, with seals made of durable fluorocarbon (FKM) elastomer. The Series 090 valve is also compliant with all relevant Restriction of Hazardous Substances (RoHS) and Conformité Européenne (CE) directives.
