Humphrey Products

Humphrey Products is a privately held U.S. manufacturer of pneumatic and fluid control valves, valve systems, regulators, fittings, and engineered fluid-control assemblies. The company serves multiple industrial markets, but it has a meaningful healthcare-facing business through its Life Science Group, which develops medical valve solutions for OEM medical devices. Its products are used in applications such as oxygen concentrators, ventilators, respirators, dialysis equipment, automated slide stainers, blood gas analyzers, and medical device reprocessing systems. Humphrey appears to operate primarily as a component and subsystem supplier rather than a therapeutics developer, so it does not have a drug pipeline in the biotech/pharma sense. The company emphasizes custom engineering, long product life, and manufacturing capabilities for pneumatic and liquid control applications.
