About Parker Precision Fluidics
Parker Precision Fluidics is the Precision Fluidics Division of Parker Hannifin Corporation, based in Hollis, New Hampshire. It designs and manufactures the miniature valves, pumps and flow and pressure controls that move gases and liquids inside medical, diagnostic and analytical instruments.
The division was formed in 2008, when Parker combined the newly acquired Hargraves Technology pump and valve business with existing product lines rooted in Pneutronics and General Valve. Porter Instrument, founded in 1968 in Hatfield, Pennsylvania, and part of Parker since 2005, adds decades of gas flow measurement experience. Porter’s industrial rotameters, mass flow controllers and regulators are now sold through Precision Fluidics.
What Parker Precision Fluidics makes
The product range covers most of the fluid path in a compact instrument. Miniature solenoid valves switch gas quickly with very low leakage, while inert liquid valves handle reagents and samples in clinical chemistry. Parker’s patented VSO proportional valves provide variable control across a range Parker cites as roughly 0.01 to 500 L/min, and they serve as the control element in the division’s miniature electronic pressure controllers.
On the pump side, diaphragm designs are built for high flow per watt in battery-powered equipment, the BTX-Connect adds a brushless motor, and the Helix piston pump covers higher-pressure needs. X-Flow thermal mass flow products, precision regulators and Porter rotameters round out measurement and control, and the Porter 3600 Series digital flow controller is designed for harsh industrial environments.
Why engineers specify Parker Precision Fluidics
- Medical-grade quality system. The Hollis operation is certified to ISO 13485:2016, and Parker valves are used in both FDA-regulated and non-regulated instruments.
- Cleanliness options. Components can be oxygen, instrument or analytically cleaned for oxygen service and trace analysis.
- One supplier, many technologies. Valves, pumps, controllers and regulators from a single source simplify qualification and supply chain management.
- Custom engineering. A customer solutions engineering team develops application-specific parts and integrated manifolds that reduce leak points and assembly work.
- Made in the USA, with Parker Hannifin’s global distribution and support behind it.
Local support from Vaughn Associates
Vaughn Associates represents Parker Precision Fluidics in Georgia, Florida and the Florida Panhandle, supporting engineering teams that design medical devices, diagnostic platforms and analytical instruments. We help engineers compare standard parts with custom options and collect the media, pressure, flow, voltage and temperature details Parker’s applications engineers ask for. We also coordinate quotes and technical questions with the factory.
We stay involved from early design reviews through production ordering. Parker’s 2019 division overview, available below, is a useful reference for the product families.
