Parker Life Sciences Delivers Broad Product Options

Liquid X

Parker Life Sciences offers Liquid X®, a 12mm isolated diaphragm solenoid valve that provides the flexibility, reliability, and application-specific performance required by today’s medical, bioanalytical, and clinical chemistry OEMs. Designed in collaboration with several global leaders in life science OEM instrumentation, Liquid X is the latest product offering from the Pneutronics X-Valve® technology platform, providing high reliability, low power consumption, and a range of features.

“We actively sought and listened to input from lead-users within our customers’ organizations and used this information to design and engineer the overall size, technical performance, and elastomer options for Liquid X," says Robert Howard, sales and marketing manager for Parker Life Sciences. “Efficient packaging and its miniature size make this valve ideal for manifold mounting. The Liquid X manifold technology offers broad product options, rapid prototyping, and significant cost advantages over the machined, injection-molded, and laminated manifold designs that are currently available on the market. Parker Life Sciences is focused on being a strategic engineering and business partner for our customers, which is why we built Liquid X to complement our adaptive fluidic and motion control technology.”

Liquid X offers perfluoroelastomer (FFKM) and ethylene propylene (EPDM) elastomer options that provide absolute repeatability in response time and performance for over five million and ten million cycles respectably. Combined with a polyetheretherketone (PEEK) body, this design guarantees Parker customers that their valves will reliably perform in harsh liquid and gaseous media, such as bleach, acids, and chlorinated solvents.

Additional performance characteristics of Liquid X include low internal volume (< 32L, to manifold interface), flow rates of 20 SLPM of air with 50 psig applied, vacuum to 35 psi operating pressure range (50 psi maximum differential), repeatable cycle times (“open” and “drop-out” response times less than 20 milliseconds), and a leak rate specification of < 0.016 sccm air at 50 psig. Liquid X meets all specifications while operating in environmental conditions ranging from 0 to 50 Celsius and requires 2 watts maximum power for 12 and 24 VDC.

An optional manifold sub-base on the Liquid X provides maximum installation flexibility. The female-threaded 10-32 or ¼-28 interface allows OEMs to choose their preferred fluid connectors on single- or multiple-station assemblies. Liquid X also offers electrical termination by incorporating 2.54 mm pitch male pins. Other optional accessories for the 12mm valve include a 18" wire leaded assembly with a friction-lock female electrical connector that ensures secure electrical termination, as well as a splash proof connector guard for wet environments.

Liquid X is available now from Parker Life Sciences.
