Description

Overview
  • Category listing of Humphrey solenoid valves covering 2-, 3- and 4-way functions across miniature, small and large size classes; includes direct-acting and pilot-operated designs suitable for compressed air, vacuum and inert gases.


Valve categories
  • Miniature 2- & 3-Way Solenoid Operated — Flow capacity <.10 Cv; ports M3 x 0.5 through 10-32 UNF
  • Small 2- & 3-Way Solenoid Operated — Flow capacity .10–1.0 Cv; ports 1/8 and 1/4 PIPE
  • Large 2- & 3-Way Solenoid Operated — Flow capacity >1.0 Cv; ports 1/4 through 3/4 PIPE
  • Small 4-Way Solenoid Operated — Flow capacity <1.0 Cv; ports 1/8 and 1/4 PIPE
  • Large 4-Way Solenoid Operated — Flow capacity >1.0 Cv; ports 1/4 through 3/4 PIPE


Product selection
  • Online navigation provides access to thousands of Humphrey valve selections. Individual product pages include CAD files, technical specifications, datasheets and ordering information. This category page provides family-level summaries and imagery; model-specific details are available on each product page.


Valve technologies
  • Direct-acting: compact, fast-switching balanced-poppet designs offering operation across the full pressure range including low pressure and vacuum; typical forms include normally closed, normally open, diverting and selecting variants.
  • Pilot-operated: use direct-acting solenoids as pilots to shift larger diaphragm- or piston-poppet directional valves, delivering higher flow relative to size and lower current consumption for a given flow.


Specifications
  • Functions: 2-way, 3-way and 4-way
  • Types: direct-acting (balanced-poppet) and pilot-operated (diaphragm-poppet, piston-poppet)
  • Media compatibility: compressed air, vacuum and inert gases
  • Body construction: precision machined or molded valve bodies for close tolerance sealing and low leak rates
  • Leak performance: many models achieve bubble-tight sealing
  • Flow performance: high-flow efficiency in compact designs
  • Port ranges: M3 x 0.5 to 10-32 UNF (miniature); 1/8 and 1/4 PIPE (small); 1/4 to 3/4 PIPE (large)
