Humphrey HK5 direct acting solenoid valve offers unmatched flexibility and tight sealing in a unique miniature design. Born from feedback of engineers with difficult 2 & 3-port applications, the valve's opposing diaphragm-poppet elastomers eliminate sliding seals and wear. Solenoid is isolated from an inert flow path, making alternate media and purity applications possible. Multi-purpose. Body is flexible, ready for our standard sub-bases, or your custom porting choices. Non-standard 4.5VDC voltage available - Contact factory. Made in the USA. RoHS and REACH compliant.
