Miniature solenoid valve expands flexibility in medical product design

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 analyser 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, 10.8 mm footprint and 50 million-cycle life for maximum reliability. And, because the new three-way configuration of the Series 090 valve can perform the same mixing and diverting functions as a pair of two-way valves, it further simplifies the design of small, high-precision gas delivery systems for oxygen and other home-care devices.

Like all Series 090 valves, the new three-way valve is built to maximise gas flow, with a flow-to-size ratio that is well suited to portable medical device applications. The valve body is moulded from polybutylene terephthalate (PBT) plastic, with seals made of durable fluorocarbon (FKM) elastomer. The Series 090 actuator combines high reliability with low power consumption, so battery life and device longevity are maximised. The Series 090 valve is also compliant with all relevant RoHS and CE directives.

“The introduction of the three-way Series 090 miniature solenoid valve offers product designers greater freedom to develop new valve and manifold solutions for analytical and therapeutic applications,” said Sven Richter, vice president of Emerson’s analytical and medical business. “Products like the new Asco Series 090 valve, together with Emerson’s Rapid Engineered Solutions capability, help our OEM, original-equipment manufacturer, customers to bring outstanding products to markets more quickly, while improving the internal production and cost efficiencies essential to long-term competitiveness.”
