New Miniature Poppet Solenoid Valve Increases Battery Life

New Miniature Poppet Solenoid Valve Increases Battery Life-Series LX valve-Precision Fluidics Division-Automation Group-Parker Hannifin CorporationSome of the biggest challenges for designing battery operated, handheld medical devices are size, weight and battery life. All three can be significantly improved by using our new miniature solenoid poppet valve.

Called the Series LX, the valve's miniature size and low weight allow easy integration into small, portable devices. Only 8 mm in size, it provides highly reliable pneumatic on/off control for critical applications, delivering up to two million open/close cycles for a standard lithium AA battery. 

Innovative two-way valve

The Series LX miniature poppet valve features a special latching device that allows the valve to remain in open or closed positions over indefinite periods of time without consuming battery power. This feature enables the solenoid poppet valve to draw current in very short pulses, significantly extending battery life.

"Developing this robust and efficient latching feature required precise integration of forces from the permanent magnet, the return spring and the flux density from the solenoid coil. Finite element analysis (FEA) tools were essential for achieving this balance during product design and helped us avoid numerous design iterations."                                                     Robert Irwin, Division Product Engineering


Other highlights of the Series LX valve are:

  • Operates at 0.4 bar (about 6 psi) and accepts common input voltages from 3V DC to 24V DC
  • Can be integrated directly onto PCBs or mounted on single or multiple-station manifolds 
  • Accepts standard flexible tubing for simple and efficient system connections

Greater design freedom for engineers

A smaller, lighter weight and longer-lasting battery pack, made possible by the Series LX valve, creates new design possibilities for engineers. In addition, engineers will appreciate the Series LX valve flow control rates, which have increased up to 50 percent over standard models, delivering up to 11 liters/min.

Design engineers will also find less heat dissipates into systems that typically accompany continuously powered solenoid valves, thereby reducing passive or active cooling needs. Further, the Series LX valve complements the highly successful X-Valve product line that offers rapid on/off response for high duty cycle applications. 

The Series LX valve characteristics of small footprint, low weight and durability are ideal for delivering reliable fluidic performance to handheld or desktop devices. Demand is rapidly growing in the life science market for portable, durable and easy-to-use devices for remote point of care, self-care, preventative testing and early diagnosis needs. Medical applications for this unique component include:

  • Infusion pumps
  • Oxygen concentrators 
  • Wound therapy  
  • Anesthesia delivery 
  • Respiratory devices

Ultimately the Series LX valve will improve end-user satisfaction and compliance because these products will be smaller, lighter weight, easier to use and longer-lasting—boosting performance and brand reputation while expanding market share.

In addition to medical applications, we see opportunity for the Series LX valve in other markets, such as: 

  • Environmental monitoring
  • Miniature fuel cells
  • Automotive lumbar support
